Question

1. choose the best answer.

______ reactions involve the transfer of electrons between reactants.
○ redox
○ acid - base
○ precipitation

1. choose the best answer.

______ reactions involve the formation of an insoluble solid.
○ acid - base
○ precipitation
○ redox

Explanation:

Question 14

Redox reactions are defined by the transfer of electrons (oxidation - reduction), acid - base reactions involve proton transfer, and precipitation reactions involve forming insoluble solids. So for the reaction with electron transfer, the answer is Redox.

Precipitation reactions are characterized by the formation of an insoluble solid (precipitate). Acid - base reactions involve proton transfer, not insoluble solid formation. So the reaction with insoluble solid formation is Precipitation.

Answer:

A. Redox
