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
Why does silver nitrate combine first with chloride ions in water and not with potassium dichromate?
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.
How would you separate lead chloride from mixture of lead chloride and silver chloride?
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.
What is the chemical reaction for silver nitrate and potassium chromate solutions?
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 =)
How could you separate silver chloride from barium chloride?
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.

What is barium nitrate plus silver chromate?
Silver chromate is not soluble in water.

What is the precipitate of silver nitrate and hydrochloric acid?
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.
Which substance is least soluble at 60 degrees C?
Silver chloride is least soluble at 60 degrees C compared to sodium chloride, potassium chloride, and calcium chloride.
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)
Is cromate soluble?
Chromate salts are typically soluble in water, except for certain heavy metal chromates like lead chromate and silver chromate, which are insoluble.
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.
Which reaction occurred when potassium chloride and silver acetate react to produce silver chloride and potassium acetate?
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.

How many soluble chlorides are there?
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.
