Osmosis
Definition- Process - Egg experiment
The flow of the solvent through a semipermeable membrane from pure solvent
to solution, or from a dilute solution to concentrated solution, is termed Osmosis
(Greek Osmos = to push).
The phenomenon of osmosis is the spontaneous passage of a pure solvent into a
solution separated from it by a semipermeable membrane, a membrane permeable
to the solvent but not to the solute.
• As time passes, the volume of the solution increases and that of the solvent
decreases. Eventually the liquid levels stop changing, indicating that the system has
reached equilibrium.

its walls is fitted with a long glass tube.

and immersed in distilled water.

d-block elements are those in which the valence electrons enters the d orbital. d- block elements are also called transition elements. Transition elements have partially filled d orbitals.
The elements in which the valence electron enters the s orbital are called s block elements.
The elements in which the valence electron enters the p orbital are called p block elements.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
2. OSMOSIS
The selective passage of solvent molecules through
a porous membrane from a dilute solution to a more
concentrated one.
3. OSMOTIC PRESSURE
The pressure required to stop osmosis.
The osmotic pressure of an ideal solution is given by MORSE EQUATION
𝜋 = MRT
𝜋 → OSMOTIC PRESSURE M → MOLARITY
R = 0.082 dm3atmmol-1K-1 T → absolute temperature
4.
5. Tonicity Measure of the osmotic pressure of
the two solutions separated by a
semipermeable membrane
There are 3 classifications of tonicity:
1. Isotonic
2. Hypertonic
3. Hypotonic
6. Isotonic
Two solutions which have
equal concentration of
solutes will have equal
osmotic pressure are
called isotonic solutions
13. REVERSE OSMOSIS
Reverse osmosis is a membrane based
filtration method that removes many
types of large molecules and ions from
solutions by applying pressure to the
solution when it is on one side of a
selective membrane.
14. If an external pressure is applied on a concentrated
solution, this pressure is distributed evenly
throughout the solution
If the applied pressure is higher than the osmotic
pressure water will flow towards the other side of
the membrane leaving solute behind
This technique is used for purification of water
18. Colloid
A colloid is a dispersion of particles of one substance (the
dispersed phase) throughout another substance or
solution (the dispersion phase).
A heterogeneous mixture of tiny particles of a substance
dispersed through a medium is called colloidal dispersion
or colloid.
20. Lyophilic vs Lyophobic
Such colloidal dispersions
in which dispersed phase
shows an affinity or
attraction for the
dispersion medium are
called Lyophilic Colloids
Such colloidal dispersions
which can not be made by
spontaneous dispersion are
called Lyophobic Colloids
21. Classification of colloids
Based on Dispersed phase and dispersion medium:
1. Sol - solid dispersed in a liquid
2. Emulsion - liquid dispersed in a liquid
3. Foam - gas particles are trapped in a liquid or solid.
4. Aerosol - particles of liquid or solid dispersed in a gas.
37. When light is shined through a
true solution, the light passes
cleanly through the solution.
However when light is passed
through a colloidal solution, the
substance in the dispersed
phases scatters the light in all
directions, making it readily seen.
