General Chemistry

2. One of the major issues that can lead to fish dying in a fish tank is the buildup of ammonia in the tank water. One of your friends Sarah is concerned about the fish in her fish tank. You remember that you learned how you can determine the relative concentrations of NH, and NH," in the fish tank with your analytical chemistry skills!You get your pH meter out, a conductivity meter, and total dissolved ammonia (NH,+ NH,") sensor and get to work. The data you collected is shown below. From this information, calculate the molar concentration of NH, and NH,* in your friends fish tank. The K, of NH, is 1.75 x 10^-5.

\begin{array}{lll} \mathrm{pH}=8.145 & \mu=2.34 \times 10^{-2} \mathrm{M} & \text { Total }\left[\mathrm{NH}_{3}+\mathrm{NH}_{4}^{+}\right]=7.06 \times 10^{-2} \mathrm{mM} \end{array}
