What is the [H3O + ] concentration of a solution formed bymixing 50.0 mL of 0.20 M HCl and 50.0 mL of 0.10 M NaOH?
Given 100.0 mL of a buffer that is 0.50 M in HOCl and 0.40 M inNaOCl, what is the pH after 10.0 mL of 1.0 M NaOH has been added?(Ka for HOCl = 3.5 ï‚´ 10ï€8 ).
What is the pH of a solution prepared by mixing 50 mL of a 0.10M solution of HF with 25 mL of a 0.20 M solution of NaF? (The pKaof HF is 3.14.)
