Monoprotic: Acetic acid (ethanoic acid) in diluted form ( 5 - 8 %) as vinegar.
Diprotic: Oxalic acid (ethanoic DI-acid) which is in spinach and rhubarb.
Triprotic: Phophoric acid (tri-hydrogen phosphoric acid) is in cola (rather diluted of coarse)
Triprotic: Citric acid (3-carboxy-3-hydroxypentanedioic acid) in citrus fruits (up to 5 - 10 %)
They all are weak acids and edible in diluted form
Vitamin C (ascorbic acid) is edible in pure form, recommended minimum dose 80 - 250 mg/day
An acid that does not disassociate completely in solution, that is the protons are not donated completely in solution as a strong acid would be. Some weal acids only donate about 1% of their protons to the solution. They are weak conductors of electricity because of this characteristic.
In pH terms, a weak acid is said to be not as acidic as strong acids. That is, the weak acid is almost 5-6 (approximately), or thereabout. A strong acid ranges from !-4, that means that that acid is very corrosive and dangerous.
strong acids are the acids which completely ionizis in water to form hydrogen ions.
is PH 4-6
It's considered a dilute acid, not a weak acid. That term has a very specific meaning. A strong acid is one that ionizes (many chemistry texts use the word "dissociate") completely in water, and a weak acid is one that doesn't completely ionize. Hydrochloric acid is a "strong" acid; hydrofluoric acid is a "weak" acid even though it's more corrosive than hydrochloric acid is. So...you could take hydrochloric acid (a strong acid) and mix it with a lot of water, get it up to pH 6, and still have a strong acid.
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
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.

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.
6
pH below 7 always is acid, base has pH above 7.
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.
