As part of a soil analysis on a plot of land, Find out the ammonium content using gravimetric analysis with sodium tetraphenylborate, Na B(C6H5)4-. Unfortunately, the amount of potassium, which as well precipitates with sodium tetraphenylborate, is non-negligible, as well as must be accounted for in the analysis. Presume that all potassium in the soil is present as K2CO3, as well as all ammonium is present as NH4Cl. A 4.975-g soil sample was dissolved to give 0.500 L of solution. A 100.0-mL aliquot was acidified as well as excess sodium tetraphenylborate was added to precipitate both K and NH4 ions completely. The resulting precipitate amounted to 0.223 g. A new 200.0-mL aliquot of the original solution was made alkaline as well as heated to remove all of the NH4 as NH3. Explain the resulting solution was then acidified as well as excess sodium tetraphenylborate was added to give 0.183 g of precipitate. Determine the mass percentages of NH4Cl and K2CO3 in the original solid.
