If 50 ml of 0.2M KOH is added to 40 ml of 0.5 M HCOOH. the pH of the resulting solutions is (Ka = 1.8 xx 10^(-4) log 18= 1.26)
20 ml of 0.4 M H_(2),SO_(4) , and 80 ml of 0.2 M NaOH are mixed. Then the p^(H) of the resulting solution is
50 ml of 0.2 M HCl is added to 30 ml of 0.1 MKOH solution. Find the pH of the solution.
50 mL of 0 . 02 M Na OH solution is mixed 50 mL of 0 . 6 M acetic acid solution, the pH of resulting solution is ( pK_(a) pf acetic acid is 4 . 76, log 5 = 0 . 70 )
A sample of NaOH weighing 0.4 g. is added to 100 ml of 0.1N H_2SO_4 solution. The nature of the resulting solution is
A buffer solution is prepared by mixing 50 mL of 0.2 M of acetic acid with .x. mL of 0.2 M of NaOH solutions. If pH of the resulting buffer solutions is 4. 7 then value of .x. is (Ka= 2xx10 ^(-5))
