231 – If to $50\,\text{mL}$ of a $1\,\text{mol/L}$ solution of weak acid (HA), drops from a $1\,\text{mol/L}$ NaOH solution are added, which statement is correct?
The salt produced from the reaction of acid and base in this reaction is neutral.
The initial pH of solution HA is independent of $K_a$ and equals zero.
During the reaction, until complete neutralization, buffering property is not observed.
By adding $50\,\text{mL}$ of NaOH solution, the pH of the solution will be greater than 7.
