![]() Ksp expression for AgCl = 0.05 mol dm -3 * 0.05 mol dm -3 = 2.5 * 10 -3 mol 2 dm -6īecause calculated value for Ksp expression is greater than Ksp value of AgCl. In this case, the silver nitrate and potassium chromate react to form silver chromate, which is insoluble in water. A precipitate is a solid that forms in a solution when two or more soluble compounds react with each other. Initial Cl - concentration after mixing = 0.05 mol dm -3 Initial Ag + concentration after mixing = 0.05 mol dm -3 When silver nitrate and potassium chromate solutions are mixed, a precipitate is formed. Then we can apply Ksp expression to check whether will there be a AgCl precipitate. Then each compound has the concentration of 0.05 mol dm -3. Let's think, when both solutions are mixed, there is no precipitate and then calculate concentration of each compound.īecause each compound is diluted by two times, concentration of NaCl and AgNO3 is reduced by half. When similar volumes of NaCl and AgNO 3 are mixed, will there be a precipitate?īoth solutions have concentrations of 0.1 mol dm -3. Observe and record the colour of any precipitate formed. If you get silver nitrate solution in your eyes, flush with water for 15 minutes and seek medical. If your skin comes into contact with silver nitrate solution, immediately wash thoroughly with soap and water. ![]() Avoid getting silver nitrate solution on your skin. Required concentration to see the precipitation Reveal answer Hydroxide precipitates tests Question Add a few drops of dilute sodium hydroxide solution. Silver nitrate is a strong oxidizer, but the solution is fairly dilute. ![]() If you immediately add one chemical to another, precipitate is also formed immediately.īut, remember that to be careful with silver nitrate and during the experiment nitrate because it is a very toxic chemical. When you are slowly adding one chemical to other chemical drop by drop, at one time, you will see a white precipitate ![]()
