Problem: Calculate the pH for each of the following cases in the titration of 35.0 mL of 0.160 M KOH(aq), with 0.160 M HCl(aq).(a) before addition of any HCl

FREE Expert Solution

We’re being asked to determine the pH before addition of any HCl

Let’s first write the balanced reaction between HCl and KOH:

▪ HCl → strong oxyacid
▪ KOH → (OH- with Group 1A ion) → strong base
▪ the reaction between a strong base and strong acid → no need to create an ICE chart

Balanced reaction:              HCl(aq) + KOH(aq) → H2O(l) + KCl(aq)
