Question

Determine whether the following salts are neutral acidic, or basic

NaCl

Aluminum nitrate

Calculate the pH of a liter of 0.125 M ammonium perchlorate solution. (kb= 1.7 x 10-5)

Calculate the pH of a liter of 0.100M potassium oxalate solution. (ka= 1.6 x 10-6)

Calculate the pH of a solution of 0.25 M Acetic acid and 0.34M Sodium acetate before and after 0.036 M NaOH is added to the solution.       Ka of HAc = 1.8 x 10 -5

Calculate the pH and molarities of all the species in a 0.150 M carbonic acid solution.

Ka = 1.5 x 10-4             Ka = 9.2 x 10-11

Explanation / Answer

Answer: 1} NaCl : As we know that it is formed by treating strong acid HCL with strong base NaOH and form a neutral salt NaCl [ Hcl + NaOH --------------> NaCl + H2O]

Hence Nacl is a neutral salt .

Aluminium nitrate is formed by when treating nitric acid and aluminium oxide [basic in nature] thats why the salt form is basic .

Hence Aluminium nitrate is basic salt .
