A 0879g sample of a cacl22h2ok2c2o4h2o solid salt mixture, Ask an Expert

Academics

A 0.879g sample of a CaCl2.2H2O/K2C2O4.H2O solid salt mixture is dissolved in 150ml of deionized water, previously adjusted to a pH that is basic. The precipitate, after having been filtered and air-dried, has a mass of 0.284g. The limiting reactant in the salt mixture was later determined to be CaCl2.2H2O.

(a)write the molecular form of the equation for the reaction.

(b) Write the net ionic equation for the reaction.

(d)How many moles and grams of excess reactant, K2C2O4.H2O, reacted in the mixture?

(e)How many grams of the K2C2O4.H2O in the salt mixture remain unreacted (in excess)?

(f)What is the precent by mass of each salt in the mixture?
