It explains that salt hydrolysis occurs when the cation or anion of a salt reacts with water, producing acidic or basic solutions depending on the relative strengths of the products. There are four types of salt hydrolysis based on the salt containing strong/weak acids and bases. Buffer solutions resist pH changes upon adding acids or bases. They work by containing a weak acid and its conjugate base or weak base and conjugate acid. Common examples are discussed along with the Henderson-Hasselbalch equation for calculating buffer pH.
Acidbasetitr
This document discusses acid-base titrations and summarizes the key steps in standardizing a sodium hydroxide (NaOH) solution and using it to determine the concentration of acetic acid in vinegar. It explains that NaOH is hygroscopic and absorbs moisture, so it must be standardized against a primary standard, potassium hydrogen phthalate (KHP), through titration. The standardized NaOH solution can then be used to titrate vinegar against it and calculate the moles and molarity of acetic acid present. It also discusses concepts like the pH at the equivalence point of a titration involving a weak acid and strong base.

acid and bases.ppt
This document provides definitions and information about acids and bases:
- It defines acids and bases according to Arrhenius and Brønsted-Lowry theories. Acids donate protons while bases accept protons.
- When an acid dissolves in water, it donates a proton to form its conjugate base and hydronium ion. Reactions between acids and bases yield conjugate acid-base pairs.
- Strong acids fully dissociate in water while weak acids only partially dissociate. The strength of an acid or base determines which direction a proton transfer equilibrium will favor.
- Water autoionizes to a small extent, forming hydronium and hydroxide ions. The ion

This document discusses salt hydrolysis and buffer solutions. It explains that salt hydrolysis occurs when the cation or anion of a salt reacts with water, producing acidic or basic solutions depending on the relative strengths of the products. There are four types of salt hydrolysis based on the salt containing strong/weak acids and bases. Buffer solutions resist pH changes upon adding acids or bases. They work by containing a weak acid and its conjugate base or weak base and conjugate acid. Common examples are discussed along with the Henderson-Hasselbalch equation for calculating buffer pH.
Acidbasetitr
This document discusses acid-base titrations and summarizes the key steps in standardizing a sodium hydroxide (NaOH) solution and using it to determine the concentration of acetic acid in vinegar. It explains that NaOH is hygroscopic and absorbs moisture, so it must be standardized against a primary standard, potassium hydrogen phthalate (KHP), through titration. The standardized NaOH solution can then be used to titrate vinegar against it and calculate the moles and molarity of acetic acid present. It also discusses concepts like the pH at the equivalence point of a titration involving a weak acid and strong base.

Chapter_15_Acids_and_Bases.ppt
This document provides an overview of acids and bases including:
- Acids have a sour taste and react with metals and carbonates/bicarbonates. Bases have a bitter taste and feel slippery.
- Arrhenius acids produce H+ ions in water while Arrhenius bases produce OH- ions. Brønsted acids are proton donors and bases are proton acceptors.
- Water autoionizes into H+ and OH- ions. The ion product of water (Kw) relates the concentrations of H+ and OH- ions in solution. The pH scale measures hydrogen ion concentration.
22 acids + bases
This document discusses acids and bases. It defines their key properties including reacting with metals, carbonates, conducting electricity, turning litmus paper colors, and neutralizing each other. It explains the theories of Arrhenius, Brønsted-Lowry, and Lewis on acids and bases. It also covers acid-base reactions, indicators, pH, titrations, strong/weak acids and bases, and acid-base stoichiometry.
Acid Base Equilibrium
A power point slide on Acids and Bases for grade 12 students. Mostly deals with ionic equilibrium, acid base theories and their simple explanations.
Acid Base Equilibrium
The PowerPoint Presentation is a set of slides associated with a discussion on Acid-Base Equilibrium.
AP Chemistry Chapter 17 Outline
The document discusses various concepts related to aqueous equilibria including:
1) The common ion effect where adding a strong electrolyte containing a common ion with a weak electrolyte decreases the ionization of the weak electrolyte.
2) Buffers and how they resist pH changes through reactions of the weak acid/base with added strong acid or base.
3) Solubility products (Ksp) and how solubility is affected by factors like common ions, pH, and complex ion formation.

Assignment: Peg Game
Create a web page that allows the user to play the Triangle Peg Game. Here are images of the starting position in several representations of the game:
The board consists of 15 holes, and 14 removable pegs. Peg colors are merely decorative. In the initial position, all 14 pegs are in the board, leaving one empty hole (empty space).
Rules: 1. You must jump a peg over another peg, but only if there is an open space. If there is more than one legal move, you may choose whichever.
2. Each peg you jump over must be removed, leaving a hole.
3. You win if only one peg is left at the end of the game.
Here is an example of the two possible first moves assuming the initial empty position is at the top of the board (at position one). The examples show only the first three rows of the board where the numbers indicate pegs and the holes are "X"'s. Thus there should be two legal moves: a peg from the third row into the top empty space, removing one of the pegs in the second row.
becomes
or
Requirements for your Web Page:
The user will play by clicking on a peg and then clicking on the empty hole to which the peg should move. This move will be legal if and only if the moving peg crosses over exactly one occupied hole and no unoccupied holes.
There should be at least three different peg colors.
If the user attempts an illegal move, display a message indicating this.
When no legal moves remain, display a message. If there is only one peg remaining, "Victory!". If two pegs remain, "So close! Try again!". If three pegs remain, "You are improving! Try again!". If four or more remain, "Better luck next time.".
There should be a button that resets the board to the default starting position (see above), and another button that starts with the position of the initial empty hole determined randomly.
For simplicity, all files, including images, should reside in the same directory/folder. Use only relative (not absolute) names for the files in your HTML.
Please provide HTML and JS code for the above question.
Extra Credit:
Move the pegs via a drag & drop mechanism. Check out the dragNdrop.html and its .js file from the source code we reviewed in class.

Make sure you include in your zip file all the .html files, as well as any image files (.gif and .jpg, for example) that your page references and any external style sheets or .js files.

Assignment 2 Application Case 6-5 Efficient Image Recognition and Cate.docx
An innovative ensemble approach to image categorization was proposed that uses a hybrid of k-nearest neighbors (kNN) and support vector machines (SVM). The approach finds the k closest neighbors to a query sample and trains a local SVM on those neighbors. This preserves distance relationships while avoiding some issues with high variance that kNN faces. Empirical tests on challenging image datasets showed the hybrid method outperformed leading learning-based parametric image classification approaches.

Aries' description of an attitude toward death he called -tame death-.docx
Aries' description of an attitude toward death he called "tame death" differs from what he called "death of the self" by which of the following characteristics? Tame death is one where the focus of attention is almost entirely on what the death means for the dying person. In tame death, death is typically faced more calmly than it is in death of the self. In death of the self, death is seen as a sort of sleep and thus is unthreatening. In death of the self, the concerns and needs of the community take precedence over those of the dying person. An "ars moriendi" developed historically around an attitude of tame death.
