Respuesta :
pH is measured from 1-14. 1=most acidic and 14=most basic. 7 is neutral. Using this you can figure out that pure water is neutral, lake water is slightly acidic, baking soda solution is slightly basic, and soapy water is basic.
Pure water which has pH = 7.0 it is Neutral in nature, Lake water which has pH = 6.5 it is Acidic in nature, Baking soda solution which has pH = 9 it is Basic in nature, Soapy water which has pH = 12 it is Basic in nature.
pH
pH is used to measure whether the substance is acidic, basic or neutral and the range is 0 - 14.
How to identify a solution is acidic, basic or neutral ?
If the pH is less than 7 then the solution is acidic in nature. If the pH is more than 7 then the solution is basic in solution. If the pH is equal to 7 then the solution is neutral in nature.
- In case of pure water pH is given 7 so pure water is neutral in nature.
- In case of lake water pH is given 6.5, it is less than 7 so lake water is acidic in nature.
- In case of baking soda solution pH is given 9 which is greater than 7, so it is basic in nature.
- In case of soapy water pH is given 12 which is greater than 7 so it is basic in nature.
Thus we can conclude that the
Pure water, pH = 7.0 = Neutral.
Lake water, pH = 6.5 = Acidic.
Baking soda solution, pH = 9 = Basic.
Soapy water, pH = 12 = Basic.
