Ka = [H+][In– ]
[HIn]
nHCl total = nHCl neutralized by tablet + nHCl neutralized by NaOH(VHCl × MHCl) = (nHCl neutralized by tablet) + (VOH– × MOH–)or (nHCl neutralized by tablet) = (VHCl × MHCl) – (VOH– × MOH–)
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
