This document provides instructions and materials for an assignment on acids and bases. It includes: 1. A list of materials needed for the assignment, including notes on acids and bases and chemistry of living things. 2. Instructions to log into LearningPoint and lead an online discussion by highlighting information and answering questions about ions, the pH scale, acids, bases, and their characteristics and uses. 3. A data table to complete with definitions and examples related to pH, acids, bases, and their properties. The document provides resources and guidance to study acids and bases, complete assignment questions, and participate in an online discussion on the topic.

3. Ion
A charged particle
Look around you and every liquid you
see will probably be either an acid or a
base. The only exception would be
distilled water. Distilled water is just
water. Most water you drink has ions in
it. It is those ions which make
something acidic or basic. (alkaline)

4. 1. Scientist use something called the “pH” scale to
measure how acidic or basic a liquid is. (base
also known as ALKALINE)
2. The scale goes from “0” to “14”
3. Distilled water is 7 (in the middle)
4. Acids are found between “0” and “6.9”
5. Bases are from “7.1” to “14”
6. Most of the liquid you find every day have a pH
near “7”, either a little below or a little above.
Why do you think this has to be true?
The pH scale we talk about is actually a
measure of the number of H+ ions in a
solution.

5. pH
Measures the # of H+ ions in a
Scale: solution (Potential Hydrogen Ions)
