Question

1. a reaction between sodium borate and acetic acid is a neutralization reaction (just like a reaction between sodium bicarbonate and acetic acid is a neutralization reaction). also just like in the reaction that you performed in this lab, all the reactants and products are colorless. the reaction equation is na3bo3(aq) + 3 ch3cooh(aq) → 3 ch3coona(aq) + h3bo3(aq) although those two reactions are similar, the one with sodium borate cannot be performed if you follow the experimental procedure in this lab handout. select the best explanation for that from the list below. (2 points) a) the chemical equation is not balanced. b) it is not possible to detect the point when the reaction is completed, and you should stop adding vinegar (if you follow the procedure as it is written in this handout). c) the reaction is very slow: you will not be able to complete the lab in a reasonable time period. d) it is not safe to perform this reaction at home.

Explanation:

The reaction between sodium borate and acetic acid is color - less like the reaction in the lab. Without a visual or other detectable indicator of completion in the given procedure, it's hard to know when to stop adding vinegar. The equation is balanced, and there's no indication of safety issues or extreme slowness related to the procedure.

Answer:

b) It is not possible to detect the point when the reaction is completed, and you should stop adding vinegar (if you follow the procedure as it is written in this handout).
