identify each of these substances as acidic, basic, or neutral. pure water, ph = 7.0 lake water, ph = 6.5 baking soda solution, ph = 9 soapy water, ph = 12
Answer
Brief Explanations:
- For pure water with (pH = 7.0), since (pH = 7) is the neutral point on the pH scale.
- For lake water with (pH=6.5), as (pH<7) indicates an acidic substance.
- For baking soda solution with (pH = 9), because (pH>7) shows a basic substance.
- For soapy water with (pH = 12), given that (pH>7) represents a basic substance.
Answer:
pure water: neutral; lake water: acidic; baking soda solution: basic; soapy water: basic.
