Get started for freeA solution has an \(\mathrm{OH}\) concentration of \(10^{-11} \mathrm{M}\). (a) Is this solution basic or acidic? Explain how you know. (b) Without using a calculator, explain how you could quickly determine the \(\mathrm{H}_{3} \mathrm{O}\) concentration of this solution. What is that concentration?
To be a weak base in water, a molecular compound must also be a weak electrolyte. What must be one of the ions it produces in water?
If \(0.378 \mathrm{~g}\) of HBr dissolved in enough water to make \(1.25 \mathrm{~L}\) of solution, what is the \(\mathrm{H}_{3} \mathrm{O}^{+}\) concentration? What is the \(\mathrm{OH}^{-}\) concentration?
Based solely on concentrations, when is an aqueous solution judged to be acidic? Give two answers to this question.
Hydrazine, \(\mathrm{H}_{2} \mathrm{NNH}_{2}\), is a weak base that can accept two protons. Draw a dot diagram for hydrazine and write equations showing how this compound accepts protons from water in two steps.
