Chapter 16: Problem 15

Calculate the hydrogen ion concentration for solutions (a) 2.42 with these \(\mathrm{pH}\) values: (b) 11.21 (c) 6.96 , (d) 15.00 .

Short Answer

Expert verified
The hydrogen ion concentrations for the given pH values are approximately: \n(a) 3.79 x 10^-3 \n(b) 7.76 x 10^-12 \n(c) 1.12 x 10^-7 \n(d) 1.00 x 10^-15

Step by step solution

01

Calculate Hydrogen Ion Concentration for pH 2.42

Start with the given pH value and use the formula \[[H^{+}] = 10^{-pH}\] to calculate the concentration of \[H^{+}\]. Substituting into this formula gives: \[[H^{+}] = 10^{-2.42}\]
02

Calculate Hydrogen Ion Concentration for pH 11.21

Repeat the same process as in step 1 but use the given pH value of 11.21 instead. Substituting into the formula gives: \[[H^{+}] = 10^{-11.21}\]
03

Calculate Hydrogen Ion Concentration for pH 6.96

Again repeat the same process as in step 1 but use the given pH value of 6.96 instead. Substituting into the formula gives: \[[H^{+}] = 10^{-6.96}\]
04

Calculate Hydrogen Ion Concentration for pH 15.00

Lastly, repeat the same process as in step 1 but use the given pH value of 15.00 instead. Substituting into the formula gives: \[[H^{+}] = 10^{-15.00}\]
