Test Chapter 7

Front

What is the solubility of Al₂(CO₃)₃?

Back

Insoluble

Front

What is a net ionic equation?

Back

A net ionic equation shows only the species that participate in a chemical reaction, omitting the spectator ions.

Front

Write the net ionic equation for the reaction between K₃PO₄ and CuSO₄.

Back

2 Cu²⁺(aq) + 3 PO₄³⁻(aq) → Cu₃(PO₄)₂(s)

Front

What is the complete ionic equation for the reaction of Pb(NO₃)₂ and 2KI?

Back

Pb²⁺ + 2NO₃⁻ + 2K⁺ + 2I⁻ → PbI₂(s) + 2K⁺ + 2NO₃⁻

Front

What precipitate forms when Pb(NO₃)₂ and K₂SO₄ are mixed?

Back

PbSO₄

Front

What is the net ionic equation for the reaction of AgNO₃ and CaCl₂?

Back

Ag⁺(aq) + Cl⁻(aq) → AgCl(s)

Front

Define a precipitate in a chemical reaction.

Back

A precipitate is a solid that forms and settles out of a liquid mixture during a chemical reaction.

Front

What is the role of spectator ions in a chemical reaction?

Back

Spectator ions are ions that do not participate in the actual chemical reaction and remain unchanged.

Front

How do you determine if a compound is soluble in water?

Back

Consult solubility rules which categorize compounds as soluble or insoluble based on their ions.

Front

What is the formula for lead(II) iodide?

Back

PbI₂
