A student mixes four reagents together, thinking that the solutions will neutralize each other. The solutions mixed together are \(50.0 \mathrm{~mL}\) of \(0.100 \mathrm{M}\) hydrochloric acid, 100.0 \(\mathrm{mL}\) of \(0.200 \mathrm{M}\) of nitric acid, \(500.0 \mathrm{~mL}\) of \(0.0100 \mathrm{M}\) calcium hydroxide, and \(200.0 \mathrm{~mL}\) of \(0.100 \mathrm{M}\) rubidium hydroxide. Is the resulting solution neutral? If not, calculate the concentration of excess \(\mathrm{H}^{+}\)or \(\mathrm{OH}^{-}\)ions left in solution.
