NaOH is an Arrhenius base because it increases the concentration of hydroxide ions when dissolved in solution.
2 answers:
<u>Answer:</u> The correct answer is True.
<u>Explanation:</u>
According to Arrhenius acid-base concept:
An acid is defined as the substance which releases hydrogen ions when dissolved in water.
A base is defined as the substance which releases hydroxide ions when dissolved in water.
As, NaOH releases hydroxide ion when it is dissolved in water. Thus, it is considered as an Arrhenius base.
The reaction of ionization of NaOH is given by the equation.
Hence, the given statement is True.

Correct answer: Option D, <span>K = 5.04 × 10^52
</span>
Reason:
We know that,
Ecell =
,
where n = number of electrons = 2 (in present case)
K = equilibrium constant.
Also, Ecell = <span>+1.56 v
Therefore, 1.56 = </span>
Therefore, log (K) = 52.703
Therefore, K = 5.04 X 10^52
