Develop both a microscopic and macroscopic model describing what happens when solutions of salt (NaCl) and sugar (c12h22011) are prepared to measure their conductivity. Describe what you would observe before and after you added salt and sugar to water.
An equilibrium mixture of this reaction(NH4HS(s)?NH3(g)+H2S(g)) at a certain temperature was found to have [H2S]= 0.350M and [NH3]= 0.276M .What is the value of the equilibrium constant (Kc) at this temperature.
