calculate the ph of a buffer solution that contains 1.5 M acetic acid (CH3COOH) and 0.3 M sodium acetate (CH3COONa) [Ka=1.8x10-5 for acetic acid]
Acetic acid (CH3COOH,CH3COOH, ?a=5.62×10−5)Ka=5.62×10−5) is a weak acid, so the salt sodium acetate (CH3COONa)CH3COONa) acts as a weak base. Calculate the pH of a 0.445 M0.445 M solution of sodium acetate.
25.00 mL of a solution containing 0.0927 M acetic acid (Ka = 1.75 x 10-5) is to be titrated with 0.1282 M NaOH. CH3COOH + NaOH → CH3COONa + H2O Calculate pH after the addition of 12.31 mL of base. (Enter your answer to three significant figures. Ignore the dissociation of water.)

Calculate ph for buffer solution with addition of 2mL of 1.0 M HCL and account for dilution. 4. Calculate pH for buffer solution with added 2mL of 1.0 M NaOH And account for dilution. The Ka of HC2H3O2 is 1.8 x 10^-5
Calculate the pH of a solution containing a salt AcNa derived from a strong base (NaOH) and a weak acid (AcH), like CH3COONa, KF, NaNO2 and so on. In this case two processes have to be considered: 1. Dissociation of the salt, within the assumption that the salt is a strong electrolyte: AcNa → Ac- + Na+, for instance: CH3COONa → CH3COO- + Na+ 2. the hydrolysis of the water Ac- + H2O ⇌ AcH + OH-, for example:...
