how many mL of 0.15M NaOH is needed to buffer the solution of 200mL 0.25M acetic acid of pH 4.30103 to a pH of 5.
another question.
solution of calcium hydroxide is a strong base which has perfectly ionized
pH = 13, if Ca = 40 O = 16, H = 1
calculate how much mass of calcium hydroxide crystals are dissolved in the solution.
i got 0.06756756 gms.. is it right?
acetic acid solution has a mass of 180 milligrams, dissolved in 2 liter solution if C-12, if Ka = 2x10 ^-5 calculate the pH of the solution
