If to 100 ml of a solution of CH3COOH with a concentration of 0.0928 N. a) 200 ml of distilled water was added. Determine its new concentration expressed to 4 decimal places, and determine the pH of the final solution. Data: pKa = 4.756 at 25°C. Consider that degree of dissociation is very small. b) If it is mixed with 100 ml of a 0.0989 N CH3COONa solution. What is the pH of the buffer solution.
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
