Question

acids have a ph below 7 and taste sour. which of the following is another property of acids?
donate hydroxide ions, oh⁻
are corrosive to most metals
turn litmus blue
feel slippery

Explanation:

To determine the correct property of acids, we analyze each option:

• "donate hydroxide ions, \( \text{OH}^- \)": Bases donate hydroxide ions, not acids (acids donate \( \text{H}^+ \) ions), so this is incorrect.
• "are corrosive to most metals": Acids react with many metals (e.g., \( \text{Zn} + \text{H}_2\text{SO}_4

ightarrow \text{ZnSO}_4 + \text{H}_2 \uparrow \)) and are corrosive to them, which is a known acid property.

• "turn litmus blue": Bases turn litmus blue; acids turn litmus red, so this is incorrect.
• "feel slippery": Bases feel slippery, not acids, so this is incorrect.

Answer:

B. are corrosive to most metals
