Question

bananas have a ph of 5. this means a banana has an excess of ____ ions and would be called a(n) ____. multiple choice h⁺; neutral solution h⁺; acid oh⁻; base oh⁻; acid h⁺; base

Explanation:

1. Recall the pH scale: A pH less than 7 indicates an acidic solution. Bananas have a pH of 5 (less than 7), so they are acidic.
2. Acids are defined as substances that release $\text{H}^+$ (hydrogen ions) in solution, meaning acidic solutions have an excess of $\text{H}^+$ ions. Bases have an excess of $\text{OH}^-$ (hydroxide ions) and a pH greater than 7. A neutral solution has a pH of 7 (equal $\text{H}^+$ and $\text{OH}^-$). So the correct pairing is $\text{H}^+$ ions and an acid.

Answer:

B. $\text{H}^+$; acid
