Which of the following is true about the reaction between sodium bromide and silver sulfate?

1. No reaction
2. Total ionic equation is identical to the net ionic equation
3. Sodium ions and sulfate ions are present in the toal ionic equation but not in the net ionic equation
4. Bromide is a spectator ion

Answered the other post above.

2.Total ionic equation is identical to the net ionic equation

To determine which statement is true about the reaction between sodium bromide (NaBr) and silver sulfate (Ag2SO4), we can first write out the chemical equation for the reaction:

NaBr + Ag2SO4 -> AgBr + Na2SO4

Now, let's go through each statement and determine if it is true or not:

1. No reaction: To determine if there is a reaction, we need to check if a new compound is formed. In this case, we can see that silver bromide (AgBr) and sodium sulfate (Na2SO4) are produced as the products. Therefore, statement 1 is not true.

2. Total ionic equation is identical to the net ionic equation: To determine the total ionic equation, we need to separate the soluble ionic compounds into their constituent ions. The total ionic equation for this reaction is:

2Na+ + 2Br- + 2Ag+ + SO4^2- -> 2AgBr + Na2SO4

To determine the net ionic equation, we eliminate the spectator ions, which are the ions that appear on both sides of the equation and do not participate in the actual reaction. In this case, the sodium ions (Na+) and sulfate ions (SO4^2-) are present on both sides of the equation and do not participate in the reaction. Therefore, statement 2 is true.

3. Sodium ions and sulfate ions are present in the total ionic equation but not in the net ionic equation: As mentioned above, the sodium ions and sulfate ions are present in the total ionic equation but not in the net ionic equation. Therefore, statement 3 is true.

4. Bromide is a spectator ion: The bromide ions (Br-) are not present on both sides of the equation and do participate in the reaction, as they combine with silver ions to form silver bromide. Therefore, statement 4 is not true.

In conclusion, the true statements about the reaction between sodium bromide and silver sulfate are:
2. Total ionic equation is identical to the net ionic equation
3. Sodium ions and sulfate ions are present in the total ionic equation but not in the net ionic equation
