Write the net ionic equation for any precipitation reaction that may be predicted when aqueous solutions of calcium iodide and chromium(III) sulfate are combined. (Use the solubility rules provided in the OWL Preparation Page to determine the solubility of compounds.)

Step-by-step answer

P Answered by Specialist

The net ionic equation is written below.

Explanation:

Net ionic equation of any reaction does not include any spectator ions.

Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.

The chemical equation for the reaction of calcium iodide and chromium (III) sulfate is given as:

$3CaI_2(aq.)+Cr_2(SO_4)_3(aq.)\rightarrow 3CaSO_4(s)+2CrI_3(aq.)$

Ionic form of the above equation follows:

$3Ca^{2+}(aq.)+6I^{-}(aq.)+2Cr^{3+}(aq.)+3SO_4^{2-}(aq.)\rightarrow 3CaSO_4(s)+2Cr^{3+}(aq.)+6I^-(aq.)$

As, chromium and iodide ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.

The net ionic equation for the above reaction follows:

$3Ca^{2+}(aq.)+3SO_4^{2-}(aq.)\rightarrow 3CaSO_4(s)$

Hence, the net ionic equation is written above.

Predict whether a precipitation reaction will occur when aqueous solutions of ammonium sulfate and calcium acetate are mixed write the net ionic equation

Step-by-step answer

Answer : YES, the reaction will give a precipitate.

Explanation : When ammonium sulfate and calcium acetate are mixed together the reaction that occurs is given below :

$(NH_{4}) _{2} SO_{4} + Ca ( C_{2} H_{3} O_{2} )_{2} -----\ \textgreater \ Ca SO_{4} + 2 [NH _{4}( C_{2} H_{3} O_{2} ) ]$

a simple displacement reaction occurs which yields Calcium Sulfate as the precipitate along with the Ammonium acetate as the by-product.

As we know calcium sulfate is a solid which is obtained, the major product will get precipitated. And rest other ions which are formed, remains in aqueous form.

The net ionic equation will be consisting of only the solid precipitate that is formed.
$Ca ^{2+} _{(aq)} + SO _{4} ^{2-} _{(aq)} ----\ \textgreater \ CaSO_{4}^{2-} _{(s)}$

Ca + CO₃²⁻ → CaCO₃

Explanation:

Solution:

Sodium carbonate = Na₂CO₃

Calcium chloride = CaCl₂

Calcium carbonate is precipitated

Reaction equation:

Na₂CO₃ + CaCl₂ → CaCO₃ + 2NaCl

The net ionic equation:

2Na⁺ + CO₃²⁻ + Ca + 2Cl⁻ → CaCO₃ + 2Na⁺ + Cl⁻

the spectator ions which both appears on both sides will cancel out and leave behind the net ionic equation:

Ca + CO₃²⁻ → CaCO₃

Chemistry

Many plants are poisonous because their stems and leaves contain oxalic acid, H2C2O4, or sodium oxalate, Na2C2O4; when ingested, these substances cause swelling of the respiratory tract and suffocation. A standard analysis for determining the amount of oxalate ion, C2O42-, in a sample is to precipitate this species as calcium oxalate, which is insoluble in water. Write the net ionic equation for the reaction between sodium oxalate and calcium chloride, CaCl2, in aqueous solution. (Use the lowest possible coefficients. Omit states-of-matter in your

H₂C₂O₄ + Ca²⁺ ⟶ CaC₂O₄ + 2H⁺

Explanation:

There are three steps you must follow to get the answer.

You must write the:

Molecular equation Ionic equation Net ionic equation

1. Molecular equation

H₂C₂O₄(aq) + CaCl₂(aq) ⟶ CaC₂O₄(s) + 2HCl(aq)

2. Ionic equation

You write the molecular formulas for the weak electrolytes and solids, and you write the soluble ionic substances as ions.

H₂C₂O₄(aq) + Ca²⁺(aq) + 2Cl⁻(aq) ⟶ CaC₂O₄(s) + 2H⁺(aq) + 2Cl⁻(aq)

3. Net ionic equation

To get the net ionic equation, you cancel the ions that appear on each side of the ionic equation.

H₂C₂O₄(aq) + Ca²⁺(aq) + 2Cl⁻(aq) ⟶ CaC₂O₄(s) + 2H⁺(aq) + 2Cl⁻(aq)

The net ionic equation is
