A prepare a 0.1 mol/L silver nitrate solution, 5g of AgNO3 was dried at 100℃ for two hours and cooled before accurately weighing out 4.25g and dissolving it in 250ml of distilled water in a conical flask.

Question

Potassium chromate indicator solution (approximately 0.25mol/L) dissolve 1g of potassium dichromate in 20ml distill water
Then unknown of sodium chloride solution was find.
put it in order and correct the above sentences

Answer 1

To prepare a 0.1 mol/L silver nitrate solution, 5g of AgNO3 was dried at 100℃ for two hours and cooled before accurately weighing out 4.25g and dissolving it in 250ml of distilled water in a conical flask.

Next, a potassium chromate indicator solution (approximately 0.25mol/L) was prepared by dissolving 1g of potassium dichromate in 20ml of distilled water.

Following this, an unknown solution of sodium chloride was found and prepared for use in the experiment.
