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
Silver chloride is 1/10 soluble than silver chromate in the cold 1/3 in hot water. That means silver will incline to precepetate as AgCl preferentially. More over if chromate will form it will convert to silver nitrate.
One method to separate lead chloride from a mixture of lead chloride and silver chloride is to dissolve the mixture in water, then add hydrochloric acid to precipitate the lead chloride while keeping the silver chloride in solution. The precipitated lead chloride can then be filtered out. Another method is to use selective precipitation by adding a potassium chromate solution, which will form a yellow precipitate with the lead chloride while leaving the silver chloride in solution.
the chemical reaction between silver nitrate and potassium chromate in generally used in a titration to look for chloride ions , and is a two step reaction: i will give you the ionic equations, which is pretty much all you need Ag+(aq) + Cl-(s) --> AgCl(s) this part of the equation caused the solution to go cloudy. when all the chloride ions are used up then the silver reacts with the chromate ions to produce the red colour you see when the end point of the precipitation is reached: 2Ag+(aq) + CrO4 2-(aq) --> Ag2 CrO4(s) which produces the red colour the amount of silver nitrate relates directly to the chloride ion concentration as it is a 1:1 ration reaction. i hope this answers your question =)
One way to separate silver chloride from barium chloride is by adding sodium chromate solution. Silver chloride will form a red precipitate while barium chloride will not react. The precipitate can then be filtered out to separate the two compounds.

Silver chromate is not soluble in water.

silver chloride (AgCl) AgNO3(aq) + KCl(aq) = AgCl (s) + KNO3 (aq) The only way to find out for your own if silver chloride or potassium nitrate is precipitated out is to look at a solubility chart.
Silver chloride is least soluble at 60 degrees C compared to sodium chloride, potassium chloride, and calcium 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)
Chromate salts are typically soluble in water, except for certain heavy metal chromates like lead chromate and silver chromate, which are insoluble.
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.
When potassium chloride and silver acetate react, a double displacement reaction occurs. The potassium from potassium acetate and silver from silver chloride swap partners to form silver chloride and potassium acetate. Silver chloride is insoluble and precipitates out of the solution.

There are many soluble chlorides, such as sodium chloride (table salt), potassium chloride, calcium chloride, and magnesium chloride. These compounds dissolve readily in water to form clear solutions.
