how can i calculate the pH of the solution obtained when 50.00mL of 0.150mol/L hydrochloric acid is added to 75mL of a 0.111 mol/L aqueous sodium hydroxide solution.

Question

need help i am stuck with that question thank you :)

Answer 1

HCl + NaOH ==> NaCl + H2O

moles HCl = M x L = ??
moles NaOH = M x L = ??
determine which is in excess and calculate H^+ (if HCl is in excess) or OH^- (if NaOH is in excess), and pH from there.
