Chapter 4, Problem 104RE

To determine

To Find: TheHydrogen ion concentration of the substance lime juice

Answer to Problem 104RE

  $[H^{+}]\approx 1.26\times {10}^{-2}M$

Explanation of Solution

Given: The pH of the lime juice is $1.9$ . Find Hydrogen ion concentration.

FORMULA USED:

  $pH=-\log [H^{+}]$

The pH of the substance is defined as

  $pH=-\log [H^{+}]$

  $\begin{array}{l}1.9=-\log [H^{+}]\\ \log [H^{+}]=-1.9\\ [H^{+}]={10}^{-1.9}\\ [H^{+}]=0.012589541179\\ [H^{+}]\approx 1.26\times {10}^{-2}M\end{array}$

Hence, the concentration of the substance is $[H^{+}]\approx 1.26\times {10}^{-2}M$
