When barium nitrate (Ba(NO₃)₂) and potassium chromate (K₂CrO₄) are mixed in a solution, a double displacement reaction occurs, resulting in the formation of barium chromate (BaCrO₄), which is a yellow precipitate, and potassium nitrate (KNO₃), which remains in solution. The reaction can be represented as:
[ \text{Ba(NO}_3\text{)}_2 + \text{K}_2\text{CrO}_4 \rightarrow \text{BaCrO}_4 (s) + 2 \text{KNO}_3 ]
The formation of the bright yellow precipitate is often used as a demonstration of a precipitation reaction.

How do you find the concentration of 3.50g of potassium chromate in 100 ml water?
K2CrO4 Molarity (concentration) = moles of solute/Liters of solution (100 ml = 0.100 Liters ) Find moles K2CrO4 first. 3.50 grams = (1 mole K2CrO4/194.2 grams) = 0.01802 moles K2CrO4 ----------------------------------------------next Molarity = 0.01802 moles K2CrO4/0.100 Liters = 0.180 M K2CrO4 -------------------------

Barium nitrate is soluble in water.
How do you make 0.25N K2CrO4 solution?
To make a 0.25N K2CrO4 solution, you need to first calculate the molecular weight of K2CrO4 (potassium chromate). Then, determine the grams of K2CrO4 needed to make the desired volume of solution at a concentration of 0.25N. Dissolve this amount of K2CrO4 in the required volume of solvent, usually water, to make the final solution.
