Question

1. what is the most likely ph for a solution of baking soda in distilled water? d) sodium

Explanation:

Step1: Identify baking - soda

Baking soda is sodium bicarbonate ($NaHCO_3$). It is a weak base.

Step2: Recall pH range of bases

The pH scale ranges from 0 - 14. Acids have pH < 7, bases have pH > 7, and neutral solutions have pH = 7. Since baking - soda is a weak base, its solution in distilled water will have a pH > 7. A typical pH for a baking - soda solution is around 8.3.

Answer:

A value greater than 7 (e.g., around 8.3)
