An acid is weak if it has a PH of seven or higher.
Weak acids have a pH around 4-7
A strong acid id PH 1 or 2 and a weak acid is a number between 5 or 6 Not 7 because that is neutral
Not very weak, it is a moderately weak acid.
Yes In theory, you could have a very weak solution of a strong acid and a stong solution of a weak acid and they would have the same pH.
Citric Acid is a weak acid. It is round about 6 on the pH scale.
pH of a strong acid would be '1' or '2' pH of a weak acid would be '5' or '6' . NB 'pH' is a logarithmic scale of the hydrogen ion content of a substance. The small/bigger the number, the greater/lesser the hydrogen ion content.
pH below 7 always is acid, base has pH above 7.
7 is the closest answer.
A pH of 9 is not acidic, it is basic. in order to be acidic the pH must be less than 7 It does not show whether the base is strong or weak as pH depends on both the strength of the acid/base as well as its concentration.
It is a weak acid.
is PH 4-6
