No, a ph of 7 is neutral. (I.e neither acid nor alkali).
No, any solution with a pH over 7 is alkaline.
It should be between 2-5 in the ph scale if dissolved in water
An acidic solution has the pH under 7.
A solution is acidic if it has a pH below 7, basic if it has a pH above 7, and neutral if it has a pH of exactly 7.
A solution with a pH below 7 is considered acidic. Common examples of acidic solutions include lemon juice, vinegar, and stomach acid.
If the solution has a pH < 7 then, it will be acidic in nature
An acidic solution. Solutions with a pH below 7 are considered acidic.
Anything less than 7
A solution with a pH of 4.7 is considered acidic. Solutions with pH values below 7 are acidic, while pH values above 7 are alkaline (basic).
A solution with a pH of 2 is more acidic than a solution with a pH of 7. The pH scale is logarithmic, so each whole number change represents a 10-fold difference in acidity. Therefore, a pH of 2 is 10,000 times more acidic than a pH of 7.
A solution with a pH of 2 is strongly acidic. Remember, 7 is neutral, anything below 7 is acid, anything above 7 is basic or alkaline.
A solution with a pH of 3 will be acidic. Substances with pH's below 7 are termed acidic, those with pH's higher than 7 are termed basic or alkaline.
