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)
The flask shown here contains 10.0 mL of HCl and a few drops of phenolphthalein indicator. The buret contains 0.130 M NaOH. What volume of NaOH is needed to reach the endpoint of the titration?
What was the initial concentration of HCl?
