Question

what is dilute acid and concentrated acid ?
please give me a right answer.
​

Answer 1

Answer:

A concentrated acid is an acid which is in either pure form or has a high concentration. ... A dilute acid is that in which the concentration of the water mixed in the acid is higher than the concentration of the acid itself. For instance, 5% sulfuric acid is a dilute acid.

Answer 2

Answer:

A concentrated acid is an acid which is in either pure form or has a high concentration. Laboratory type sulfuric acid (about 98% by weight) is a concentrated (and strong) acid. A dilute acid is that in which the concentration of the water mixed in the acid is higher than the concentration of the acid itself.

I hope it's correct.
