Problem: Potatoes can be peeled commercially by soaking them in a 3-M to 6-M solution of sodium hydroxide, then removing the loosened skins by spraying them with water. Does a sodium hydroxide solution have a suitable concentration if titration of 12.00 mL of the solution requires 30.6 mL of 1.65 M HCI to reach the end point?

FREE Expert Solution

The reaction of NaOH with HCl is as follows:

NaOH(aq) + HCl(aq) → NaCl(aq) + H2O(l)

Recall that molarity is defined by:

We first need to determine the moles of HCl present from the given molarity and volume:
