Question

According to the chart, which statement is MOST accurate?

A) HCl has the highest pH and highest [H+] concentration.

B) KOH has the highest pH and the highest [OH-] concentration.

Eliminate

C) KOH has the lowest pH and the highest [OH-] concentration .

D) H3BO3 has a relatively low [H+] concentration as well as a relatively low pH.

Answer 1

Answer:b is the most accurrate

Explanation:

As koh has the highest ph as it is more basic and have highest concentration of oh as it is strong base

Answer 2

Answer:

Option B) KOH has the highest pH and the highest [OH-] concentration.

Explanation:

The basicity of a substance increases as the dissociation coefficient increases. Generally, a strong base strongly ionizes in water according to the reaction:

$KOH + H_{2}O = K^{+} + OH^{-}$

Hence, from the table, KOH is a strong base.
