Question
KA1 Identify the correct response(s).
Neutral substances have:
- equal numbers of H and OH ions
- high numbers of OH ions
- corrosive properties
- a pH of 7
Solution
To determine which responses are correct regarding neutral substances, let's analyze each option:
-
Equal numbers of H⁺ and OH⁻ ions: This statement is true. Neutral substances have equal concentrations of hydrogen ions (H⁺) and hydroxide ions (OH⁻).
-
High numbers of OH⁻ ions: This statement is false. Neutral substances do not have a high concentration of OH⁻ ions; they maintain a balance with H⁺ ions.
-
Corrosive properties: This statement is false. Neutral substances are not corrosive; corrosivity is typically a property of acids or bases.
-
A pH of 7: This statement is true. Neutral substances, like pure water, have a pH of 7.
Final Answer
The correct responses are:
- Equal numbers of H⁺ and OH⁻ ions
- A pH of 7
