Which of the following pairs of reactants is not correctly listed with its product solution? A. Weak base-strong acid reactants—
more acidic solutions B. Weak acid-strong base reactants— more basic solutions C. Strong base-strong acid reactants—neutral solutions D. Strong acid-strong base reactants—more acidic solutions
D. Strong acid-strong base reactants—more acidic solutions
Explanation:
A strong acid and strong base solution will neutralize each other. The solution has an equal number of proton (H⁺) and hydroxide ions (OH⁻).
For example, HCl + NaOH → NaCl + H₂O
NaCl is a neutral salt where are HCl and NaOH are strong acids and base respectively. NaCl solution has a pH close 7.0 making it neither acidic nor basic.
For example, the relative rate of a reaction at 20 seconds will be 1/20 or 0.05 s -1, while the average rate of reaction over the first 20 seconds will be the change in mass over that period, divided by the change in time.
