Two types: silver (Ag+) and chromate (CrO4-2) And within the formula (Ag2CrO4) there are two silver ions and one chromate ion for a total of three ions.

Write the solubility product expression for silver chromate.?

The solubility product expression for silver chromate (Ag2CrO4) is Ksp = [Ag+]²[CrO4²-], where [Ag+] represents the concentration of silver ions and [CrO4²-] represents the concentration of chromate ions in the saturated solution.


Why pottasium chromate is used as indicator in argentometric titration?

Potassium chromate is used as an indicator in argentometric titrations because it forms a red precipitate (silver chromate) in the presence of excess silver ions. This color change signals the end point of the titration, where all the chloride ions have reacted with silver ions. This makes it easy to visually detect when the reaction is complete.

Why is potassium chromate indicater used in silver nitrate titration determining in water chloride?

At the end point, so after all Cl- has reacted with Ag+, a brown-red precipitate of silver chromate (Ag2CrO4), is formed. (Argentometric indicator)Description:The solubility of silver chromate is slightly higher than that of silver chloride. So, in a mixture of both ions silver chloride will be formed. Only when no chloride is left silver chromate will be formed and precipitated out.Prior to the endpoint the solution has a milky lemon yellow appearance, due to the color of the chromate ion and the precipitate of silver chloride already formed.When approaching the endpoint, additions of silver nitrate lead to steadily slower disappearing red colorations. When the red brownish color remains (with grayish spots of silver chloride in it) the endpoint of titration is reached. (wikipedia)

How many moles of silver chromate will be formed when a silver nitrate solution of known concentration is added to a specified volume of potassium chromate solution of the same concentration?

The number of moles of silver chromate formed will depend on the stoichiometry of the reaction between silver nitrate and potassium chromate. You need to know the balanced chemical equation, as well as the exact volumes and concentrations of the silver nitrate and potassium chromate solutions to calculate the number of moles of silver chromate formed.
