Problem 4
Write the \(K_{\mathrm{a}}\) expression for \(\mathrm{HNO}_{3}\).
Problem 8
The acids in Table 2 are divided into two groups: those with \(K_{\mathrm{a}}>1\) and those with \(\mathrm{K}_{\mathrm{a}}<1\). Describe each of these two groups in terms of percent dissociation.
Problem 20
Use the value of \(K_{\mathrm{w}}\) to calculate the hydronium ion concentration and the hydroxide ion concentration in pure water.
