Solubility

Solubility. ~A measure of how soluble something is. Nothing is completely soluble or completely insoluble. Increasing the temperature normally increases the amount of a solid solute a solution can hold. Gases dissolved in a liquid. Colder solutions hold more of a gaseous solute.

Chemistry:

A 1.00 L solution is prepared by placing 0.10 moles of a weak acid (HA) and 0.050 moles of its conjugate base NaA. Determine the pH of the solution. The Ka of the HA is 1.4 x 10 -5. Chemistry:. HA + H 2 O ? H 3 O + + A -. I. C. E. 0.10 0 0.050.

Molality

Molality. (these calculations are not in your book) Molality is said molal and is represented by a lower case m molality= mol solute/ kg of solvent. Problem. 2.1 kg of sodium chloride is dissolved in 45 kg of water. What is the molality of the solution?

What is the equilibrium chemical equation?

Calculate the pH of a 1.00 L solution that is 0.150 M in Benzoic acid (HC 7 H 5 O 2 ) and 0.050 M in potassium benzoate (KC 7 H 5 O 2 ). The pK a of benzoic acid is 4.20. This is a buffer solution since it contains a weak acid and its conjugate base (a salt of the acid).
