Q

# Calculate the pH of the resultant mixtures: b) 10 mL of 0.01M H_2SO_4 + 10 mL of 0.01M Ca(OH)_2

7.66     Calculate the pH of the resultant mixtures:

b)      10 mL of 0.01M H2SO4 + 10 mL of 0.01M Ca(OH)2

In this case, both the solutions have the same number of moles of $H^+$and $OH^-$, therefore they both can get completely neutralised. Hence the  $pH$ = 7.0
