The reactions shown below occur between an aqueous cation and a solid metal. Determine if purple metal will react with a solution of red cations.

Use the reactions below to list A, B, C, and D by increasing order of their reducing ability.

A + B⁺ → no reaction

C + D⁺ → C⁺ + D

A + C⁺ → A⁺ + C

B + C⁺ → B⁺ + C

Can H₂SO₄ dissolve Ag? If so, write the balanced equation for the reaction. 

How much 4.0 M of H₂SO₄ in mL is needed to dissolve 3.20 g of Ag?

Consider the following substances: 5.00 g powdered platinum and 5.00 g powdered chromium metal. Identify the metal that will react with 650.0 mL of a 0.500 M nickel (II) nitrate solution. Assuming that the reaction goes to completion, calculate the molarity of the Ni²⁺ ions remaining after the reaction is complete.

The following solutions were mixed and organic solvent added, according to the data below:

                              Solutions                             Organic layer color

Experiment 1:  NaCl (aq) and I₂ (aq)                        yellow

Experiment 2: NaCl (aq) and F₂ (aq)                       yellow

Experiment 3: NaI (aq) and  Cl₂ (aq)                       yellow

Select the best choice:

a) only I₂ is able to displace Cl ions

b) I₂ and F₂ are unable to displace Cl ions

c) F₂ capable of displaying Cl and I ions

d) I₂ and F₂ are both able to displace Cl ions
