Answer and Explanation:

We have to identify the anion (negatively charged ion) and the positive ion to form each compound. The sum of the positive and negative charges will be equal to 0 for a neutral compound.

Chloride: the anion is Cl⁻ (1 negative charge).

Magnesium (Mg²⁺) + Chloride (Cl⁻) : MgCl₂

Sodium (Na⁺) + Chloride (Cl-): NaCl

Zinc (Zn²⁺) + Chloride (Cl-): ZnCl₂

Lithium (Li⁺) + Chloride (Cl-) : LiCl

Lead(II) (Pb²⁺) + Chloride (Cl⁻): PbCl₂

Calcium (Ca²⁺) + Chloride (Cl⁻): CaCl₂

Iron(II) (Fe²⁺) + Chloride (Cl⁻): FeCl₂

Iron(III) (Fe³⁺) + Chloride (Cl⁻): FeCl₃

Potassium (K⁺) + Chloride (Cl): KCl

Nitrate: the anion is NO₃⁻ (1 negative charge).

Magnesium (Mg²⁺) + Nitrate (NO₃⁻) : Mg(NO₃)₂

Sodium (Na⁺) + Nitrate (NO₃⁻): NaNO₃

Zinc (Zn²⁺) + Nitrate (NO₃⁻): Zn(NO₃)₂

Lithium (Li⁺) + Nitrate (NO₃⁻) : LiNO₃

Lead(II) (Pb²⁺) + Nitrate (NO₃⁻): Pb(NO₃)₂

Calcium (Ca²⁺) + Nitrate (NO₃⁻): Ca(NO₃)₂

Iron(II) (Fe²⁺) + Nitrate (NO₃⁻): Fe(NO₃)₂

Iron(III) (Fe³⁺) + Nitrate (NO₃⁻): Fe(NO₃)₃

Potassium (K⁺) + Nitrate (NO₃⁻): KNO₃

Sulphate: SO₄²⁻ (2 negative charges)

Magnesium (Mg²⁺) + Sulphate (SO₄²⁻) : MgSO₄

Sodium (Na⁺) + Sulphate (SO₄²⁻): Na₂SO₄

Zinc (Zn²⁺) + Sulphate (SO₄²⁻): ZnSO₄

Lithium (Li⁺) + Sulphate (SO₄²⁻) : Li₂SO₄

Lead(II) (Pb²⁺) + Sulphate (SO₄²⁻): PbSO₄

Calcium (Ca²⁺) + Sulphate (SO₄²⁻): CaSO₄

Iron(II) (Fe²⁺) + Sulphate (SO₄²⁻): FeSO₄

Iron(III) (Fe³⁺) + Sulphate (SO₄²⁻): Fe₂(SO₄)₃

Potassium (K⁺) + Sulphate (SO₄²⁻): K₂SO₄

Carbonate: CO₃²⁻ (2 negative charges)

Magnesium (Mg²⁺) + Carbonate (CO₃²⁻) : MgCO₃

Sodium (Na⁺) + Carbonate (CO₃²⁻): Na₂CO₃

Zinc (Zn²⁺) + Carbonate (CO₃²⁻): ZnCO₃

Lithium (Li⁺) + Carbonate (CO₃²⁻): Li₂CO₃

Lead(II) (Pb²⁺) + Carbonate (CO₃²⁻): PbCO₃

Calcium (Ca²⁺) + Carbonate (CO₃²⁻): CaCO₃

Iron(II) (Fe²⁺) + Carbonate (CO₃²⁻): FeCO₃

Iron(III) (Fe³⁺) + Carbonate (CO₃²⁻): Fe₂(CO₃)₃

Potassium (K⁺) + Carbonate (CO₃²⁻): K₂CO₃

Hydroxide: OH⁻ (1 negative charge)

Magnesium (Mg²⁺) + Hydroxide (OH⁻): Mg(OH)₂

Sodium (Na⁺) + Hydroxide (OH⁻): NaOH

Zinc (Zn²⁺) + Hydroxide (OH⁻): Zn(OH)₂

Lithium (Li⁺) + Hydroxide (OH⁻): LiOH

Lead(II) (Pb²⁺) + Hydroxide (OH⁻): Pb(OH)₂

Calcium (Ca²⁺) + Hydroxide (OH⁻): Ca(OH)₂

Iron(II) (Fe²⁺) + Hydroxide (OH⁻): Fe(OH)₂

Iron(III) (Fe³⁺) + Hydroxide (OH⁻): Fe(OH)₃

Potassium (K⁺) + Hydroxide (OH⁻): KOH

Phosphate: PO₄³⁻ (3 negative charges)

Magnesium (Mg²⁺) + Phosphate (PO₄³⁻): Mg₃(PO₄)₂

Sodium (Na⁺) + Phosphate (PO₄³⁻): Na₃PO₄

Zinc (Zn²⁺) + Phosphate (PO₄³⁻): Zn₃(PO₄)₂

Lithium (Li⁺) + Phosphate (PO₄³⁻): Li₃PO₄

Lead(II) (Pb²⁺) + Phosphate (PO₄³⁻): Pb₃(PO₄)₂

Consider a culture medium on which only gram-positive organisms such as staphylococcus aureus colonies can grow due to an elevated nacl level. a yellow halo surrounds the growth, indicating the bacterium fermented a sugar in the medium, decreasing the ph as a result and changing the color of a ph indicator chemical. this type of medium would be referred to as a differential and enrichment culture.
