Question

5.00 g of solid silver nitrate AgNO3 is added to 100ml of deionized H2O to make a substance that can test the presence of chlorine in water. Identify in the word problem each of the following: (1pt each).

What is the solvent?

What is the solute?

What is the solution?

Answer 1

Answer:

The solvent is deionised water

The solute is AgNO3

The solution is [Ag(aq) + NO3(aq)-]

Explanation:

• This is because it contains no ions which would otherwise react with AgNO3 thus AgNO3 just disolves releasing free Ag+ and NO3- . The resiltant solution can test for Cl presence
• AgNO3 is a soluble salt in water thus disolves in water
• AgNO3 disolves releasing free ions which can be called ionisation
