Problem: Calculate the pH of the resulting solution if 27.0 ml of 0.270 M HCl is added toa) 32.0 ml of 0.270 M NaOH(aq)b) 37.0 ml of 0.320 M NaOH(aq)

FREE Expert Solution

NaOH is a strong base while HCl is a strong acid. No ICE or ICF chart is needed.


A. First, calculate the amount of acid and base that will react

molarity (volume) → moles

Recall:

molarity (M)=moles of soluteL of solution


*convert mL to L → 1 mL = 10-3 L
