Why potassium chromate is more soluble than silver chloride?
due to the solubility product constant(ksp)
What is the compound name for Ag2Cr2O7?
Silver Chromate Ag=Silver CrO4= Chromate(a polyatomic ion)
Why does silver nitrate combine first with chloride ions in water and not with K2CrO4?
What really combines is silver ion. Silver chloride is 1/10 soluble than silver chromate in the cold, 1/3 in hot water. That means silver will incline to precipitate as AgCl preferentially. Moreover, if chromate will form it will convert to silver chloride
What color is Silver chromate dissolved in water?
The chromate ion (CrO4-2) has yellow colour so all the chromate compounds including silver chromate is yellow in colour.
Is silver chromate soluble in water?
No

What is barium nitrate plus silver chromate?
Silver chromate is not soluble in water.
What color is Silver chromate dissolved in water?
The chromate ion (CrO4-2) has yellow colour so all the chromate compounds including silver chromate is yellow in colour.
How many ions in silver chromate?
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.
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)
