Question

If 1 mole of HCl(aq) was reacted with 2 moles of NaOH(aq), the pH of the solution would be?

Acid or base

Answer 1

HCl + NaOH ---> NaCl + H₂O
1 mol...1 mol

1 mol of HCl + 1 mol of NaOH.
We used 2 moles of NaOH. ---> too much

Limiting reactant: HCl
Excess reactant NaOH ---> pH of the solutnion would be base (pH>7)
