A two-liter sample of mineral water was evaporated to a small volume, following which the potassium ion was precipitated with excess sodium tetraphenylboron: K*1 + NaB(C.Hs)4 → KB(CHs)4 19) The precipitate was filtered, washed and redissolved in acetone. The analysis was completed by a Mohr titration that required 43.85-mL of 0.03941M AGNO3: KB(C,Hs)4 (5) + Ag → AgB(CaHs)a ce) + K** Calculate the potassium ion concentration (parts per million) of the water sample. Molar Mass: K = 39.10

A two-liter sample of mineral water was evaporated to a small volume, following which the potassium ion was precipitated with excess sodium tetraphenylboron: Ki + NaB(CHs))4 → KB(C&Hs)4 15) The precipitate was filtered, washed and redissolved in acetone. The analysis was completed by a Mohr titration that required 43.85-mL of 0.03941M AGNO3: KB(C,Hs)4 (5) + Ag → AgB(C&Hs)4 (e) + K** Calculate the potassium ion concentration (parts per million) of the water sample. Molar Mass: K = 39.10
