Find molarity of solution NaCl given ion concentration
A 0.500 g sample of AgCl was mixed with 250 mL sodium chloride solution of unknown molarity. In order to find the molarity of sodium chloride the amount of dissolved silver ion was monitored with an ion selective electrode at 25 C. The electrode registered the concentration of Ag+ ion to be 3.75x10^-8 M. Calculate the concentration of molarity of the NaCl.

Question
A 20.0 mL sample solution contains unknown amount of bromide ion (Br). To this solution was added the solution that contains plenty of AgNO3. AgBr precipitates were formed. The precipitate were filtered and measured to be is 0.6964 g. What is the molarity of bromide ion in the original sample solution? The molar mass of Br = 80.0 g; the molar mass of AgBr = 188 g. (Solution) AgNO, is soluble and thus exists Ag+ ion and NO3-ion. Ag+...

To solve stoichiometry problems, you must always calculate numbers of moles. Recall that molarity, M, is equal to the concentration in moles per liter: M=mol/L When solutions of silver nitrate and sodium chloride are mixed, silver chloride precipitates out of solution according to the equation AgNO3(aq)+NaCl(aq)→AgCl(s)+NaNO3(aq) Part A What mass of silver chloride can be produced from 1.91 L of a 0.219 M solution of silver nitrate? Express your answer with the appropriate units. Part B The reaction described in...
