Answer:
C. hydrocyanic acid
Explanation:
The mixture of a weak acid (As hydrocyanic acid, HCN), with its conjugate base (Na⁺CN⁻) produce a buffer effect in the solution due the equilibrium:
HCN ⇄ CN⁻ + H⁺
Now, when NaOH (A base) is added to the mixture, the reaction with <em>HCN </em>is:
NaOH + HCN → Na⁺CN⁻ + H₂O
As the OH⁻ of NaOH are not affecting directly the H⁺ concentration, <em>the pH does not increase dratically.</em>

Right answer is:
<em>C. hydrocyanic acid

When the potato is put into the distilled water, it will absorb the water. The water is trying to dilute the salt inside the potato.
What is the meaning of concentrated?
The concentration of a solution is a measure of the amount of solute that has been dissolved in a given amount of solvent or solution.
When the potato is put into the distilled water, it will absorb the water. The water is trying to dilute the salt inside the potato.
Since potatoes already contain sugar, less water will diffuse out of the potato placed in sugar water. The slice placed in water will be rigid since it will absorb water.
