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)
What is a Solution Hollows?
A Solution Hollow is a feature in a Limestone Pavement Formed by Carbonation
When you mix a solid and a liquid what are two indications that a solution was formed and not a new compound?
If a solution is formed after the water evaporation the initial solid is obtained.
Does uranium ignite in air?
Yes, uranium is oxidized in air even at room temperature (surface oxidation) but at high temperature the oxidation is total; the formed oxide is U3O8.
What is the formula for the cation formed when aluminum metal is oxidized?
4Al(s) + 3O2(g) --> 2Al2O3(s) where Al has an oxidation number of 3+
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?
how many moles are there in 56.0 grams of silver nitrate?
How many moles of silver chromate could be formed from 50.00ml of 0.0500m silver nitrate solution and 100.00ml of 0.0600m potassium chromate solution?
Ag+ = 50 x 0.05 = 2.5 millimoles CrO4^2- = 100 x 0.06 = 6 millimoles Ag2CrO4 moles = 1.25 x 10^-3 moles formed.

Would copper melt in acid?
Only if the acid is above the melting point of copper. However, the copper might dissolve in acid if the acid is oxidizing. If it did, copper ions would be present in the solution formed, but there would not be an metallic copper in it.
What is solute from solution?
During a chemical reaction, a precipitate is sometimes formed in the solution. The precipitation is the solid that is formed within a solution.
How many grams of copper II oxide can be formed by oxidizing 1 kg of copper?
1654 grams exactly
