Question

eddies chemistry teacher has asked the class to add various household substances to this scale of acids and bases. eddie must decide where add baking soda, ph 9. eddie should insert baking soda, ph 9, as a a weak acid b weak base c strong acid

Explanation:

Step1: Recall pH scale properties

A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic.

Step2: Analyze baking - soda's pH

Baking soda has a pH of 9, which is greater than 7, so it is a base.

Step3: Determine base strength

Weak bases have a moderate ability to accept protons. Strong bases completely dissociate in water. Baking soda (sodium bicarbonate) is a weak base as it does not completely dissociate in water.

Answer:

B. weak base
