Answer: pH = 2
Explanation: pH is the measure of acidity or alkalinity of a solution.
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. And a solution having more pH will have less amount of \(H^+\) concentration.
Acids have pH ranging from 1 to 6.9 , neutral solutions have pH of 7 and bases have pH ranging from 7.1 to 14.
Strong acids which dissociate completely when dissolved in water and have high concentration of \(H^+\) will have low pH and vice versa.
