Question

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

Explanation:

Baking soda (pH 9) is basic (pH > 7). Strong bases (like NaOH, KOH) are at the bottom. Baking soda is a weak base (similar to \(NH_3\) in the scale), not strong. So it's a weak base.
