Question

The lower the ph of a solution, the ______.

Answer 1

Answer: b.more acidic the solution

Explanation:

pH is the measure of acidity or alkalinity of a solution.  Acids are substances which gives $H^+$ ions when dissolved in water.

$HX\rightarrow H^++X^-$

pH is calculated by taking negative logarithm of hydrogen ion concentration.

$pH=-\log [H^+]$

$pH=log\frac {1}{H^+}$

Thus as pH and $H^+$ are inversely related, a solution having lower pH will have more amount of $H^+$ concentration , a lower amount of $OH^_$ concentration and will be more acidic.

Answer 2

B

a and c are unrelated
d: ph will increase
