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 done

Answer

Answer:

  1. pure water, pH = 7.0: neutral
  2. lake water, pH = 6.5: acidic
  3. baking soda solution, pH = 9: basic
  4. soapy water, pH = 12: basic

Explanation:

Step1: Recall pH - scale rules

Substances with pH = 7 are neutral.

Step2: Analyze pure water

Since pH of pure water is 7.0, it is neutral.

Step3: Analyze lake water

pH of 6.5 < 7, so it is acidic.

Step4: Analyze baking soda solution

pH of 9 > 7, so it is basic.

Step5: Analyze soapy water

pH of 12 > 7, so it is basic.
