The pH of a solution prepared by mixing 45 mL of 0.183 M KOH and 65 mL of 0.145 M HCl is ?.

  • chemistry -

    moles KOH = M x L = ??
    moles HCl = M x L = ??
    Which is in excess. by how much? That will be H^+ (if HCl is in excess) or OH^- (if KOH is in excess) and you determine pH from that final value.
