the pH scale runs from 1-14. 1 to 6.9 is considered an acid with 1 being the strongest acid and 6.9 being an extremely almost neutal acid. 7 is neutral. 7.1 to 14 is a base with 14 being the strongest base and 7.1 being a really weak base. Water is supposed to be neutral thus giving it a pH of 7.
The easy answer is...No. Plain water, H2O, has a pH of 7, which is known as neutral on the pH scale. Acids have a pH lower than 7, whereas bases have a pH higher than 7. The pH scale technically only goes up to 14 and down to 0.
Yeah all substances has a pH, whether acidic, alkaline or neutral.
It's a PHYSICAL Property!!!
I disagree - since it is a measure of the Hydrogen Ion concentration it can be argued it is a chemical property
As per the defination of pH , relates only with H+ and OH- that mean only aqueous system can give this relationship. so i think solids don't have pH
Yes, even if that pH is neutral.
The neutral pH is 7,00.
7 The pH of a neutral substance is 7. Anything higher than 7 is alkaline or basic, and anything lower than 7 is acidic.
Ketchup is not considered to be a neutral substance. Ketchup is considered to be an acidic substance with a low pH.
A neutral solution
Sodium chloride, NaCl, for example is of neutral pH and conductive in solution or in molten state. It is a salt.
That the substance is neutral, neither basic or acidic. Distilled, deionised water has a pH of 7
pH ranges from 0 - 14. Ph of 0 - 6 are acidic and will turn litmus paper 'red. pH = 7 is neutral ( water) pH of 8 - 14 is alkaline and will turn litmus paper 'blue'.
Neutral substance has a pH of 7
A substance with a pH of 7 is not acidic nor is it basic. It is a neutral substance.
This substance is neutral.
Methane (CH4) has a neutral pH, around 7
Neutral.
It's a neutral substance, with a pH of 7.
7 The pH of a neutral substance is 7. Anything higher than 7 is alkaline or basic, and anything lower than 7 is acidic.
Ketchup is not considered to be a neutral substance. Ketchup is considered to be an acidic substance with a low pH.
A neutral solution
The pH is the negative log of the concentration of hydronium ions. (pH=-log [H3O+]) If the pH is high, the substance is basic. If it is low the substance is acidic. When the pH is exactly 7 the substance is neutral.
Most acidic is substance of pH of 2, then of pH of 5 and the substance of pH 7 is neutral and the substance of pH 11 is basic
