Question

Strontium compounds are often used in flares because their flame color is bright red. One industrial process to produce low-solubility strontiun) compounds (that are less affected by getting wet) involves the reaction of aqueous solutions of strontium nitrate and sodium carbonate. Write the balanced molecular equation, the total ionic equation and the net ionic equation for this reaction.

Answer 1

Answer:

Sr(NO3)2 + Na2CO3 --------> SrCO3 + 2NaNO3

Total ionic equation;

Sr^2+ + NO3^- + Na^+ + CO3^2- -----> SrCO3 + 2NaNO3

Net ionic equation;

Sr^2+ + CO3^2- -----> SrCO3

Explanation:

The molecular equation shows the reactions of the compounds to give the products. It shows the molecular formula of reactants and products.

The total ionic equation shows the ions that recombine to form the products of the reaction.

The net ionic shows the major ionic reaction that took place in the system.

Hence, the net ionic equation explicitly shows the major species that are involved in a reaction, while a complete ionic equation includes the spectator ions.
