Chapter 12 Salt Practice on salt solubility rules and state symb

All nitrate salts are soluble except

• lead and silver

• lead, calcium and barium

• sodium, potassium and ammonium

• There is no exception all nitrates are soluble.

All chloride salts are soluble except

• lead and silver

• lead, calcium and barium

• sodium, potassium and ammonium

• There is no exception all nitrates are soluble.

All sulfate salts are soluble except

• lead and silver

• lead, calcium and barium

• sodium, potassium and ammonium

• There is no exception all nitrates are soluble.

All hydroxide are insoluble except

• lead and silver

• lead, calcium and barium

• Group I metal hydroxide

• some of Group II metal hydroxide

Answer explanation

recall from chapter 11 acids and bases where all group I metal base and group II metals (from calcium onward down the group) base are soluble in water.

All carbonates are insoluble except

• lead and silver

• lead, calcium and barium

• Group I metal carbonates

• Group II metal carbonates

Is magnesium sulfate soluble?

• Soluble

• insoluble

What is/are the possible physical state symbols for magnesium sulfate?

• s

• aq

• l

• g

Answer explanation

For soluble substances, their state symbols can be in solid (s) or aqueous state (aq).

Knowing the state symbols of the substances will help you in constructing chemical equations and ionic equations as only substance in aqueous (aq) state can be dissociated into ions.

Is calcium sulfate soluble?

• Soluble

• insoluble

What is/are the possible physical state symbols for calcium sulfate?

• s

• aq

• l

• g

Answer explanation

For insoluble substances, their state symbols can only be in solid (s) state.

Knowing the state symbols of the substances will help you in constructing chemical equations and ionic equations as only substance in aqueous (aq) state can be dissociated into ions.

Is copper(II) chloride soluble?
