Problem: Calculate the pH of the resulting solution if 35.0 mL of 0.350 M HCl(aq) is added toa) 25.0 mL of 0.450 M NaOH(aq)ph=____b) 45.0 mL of 0.350 M NaOH(aq).ph= ______

FREE Expert Solution

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

▪ HCl → strong binary acid
▪ NaOH → (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) + NaOH(aq) → H2O(l) + NaCl(aq)



a) 35.0 mL of 0.350 M HCl(aq) is added to 25.0 mL of 0.450 M NaOH(aq)

Step 1: Calculate the initial amount (in moles) of the HCl and NaOH
