InterviewSolution

1.	Calculate the resultant pH of a solution when 20 mL 0.1 N NaOH is mixed with 20 mL of 0.05 M `Ca(OH)_(2) " at " 25^(@)C`
Answer» (i) calculation of net `H^(+)` ion concentration in the mixture (ii) calculation of the total number of `OH^(-)` ions generated from the given volume of NaOH and `Ca(OH)_(2)` (iii) calculation of concentrationof `OH^(-)` ions in the resultant solution (iv) calculation of pOH (v) calculation of pH from the value of pOH at `25^(@)C` (vi) 3
