Answer:
pure water, pH = 7.0 (Neutral)
lake water, pH = 6.5 (Acidic)
baking soda solution, pH = 9 (Alkaline)
soapy water, pH = 12 (Alkaline)
Explanation:
The degree of acidicity or alkalinity of a solution can be determined on a pH meter. A pH below 7 is acidic; a pH of 7 is neutral; a pH value of above 7 is alkaline.
Pure water is neutral with pH = 7.0, lake water is acidic with pH=6.5, baking soda solution is alkaline with pH = 9 and soapy water is alkaline with pH = 12.
What is pH?
pH measures the acidic, basic level of a liquid or other substance.
- The pH measurement ranged from 0 - 14 where 7 is neutral, pH less than 7 indicates acidity and pH above 7 indicate alkalinity.
Therefore, Pure water is neutral with pH = 7.0, lake water is acidic with pH=6.5, baking soda solution is alkaline with pH = 9 and soapy water is alkaline with pH = 12.
