Chapter 15, Problem 120QRT

Interpretation Introduction

Interpretation:

The two invalid assumptions that given $\text{pH}\text{5}\text{.89}$ of $1.0\times {10}^{-7}\text{mol}/\text{L}$ acetic acid solution has to be stated.

Concept Introduction:

According to Arrhenius's theory, “an acid is defined as a species which donates a proton”.  The weak acid that dissociates partially $\left(\sim 1\%\right)$ in water and the strong acid dissociates completely $\left(\sim 100\%\right)$ in water.  Acid releases proton in water.  The number of ${\text{H}}^{+}$ ions produced by a weak acid is less than that produced by a strong acid of the same molarity.
