Hello all, How are you?
I was studying english grammer and I found s.th strange.
It was written that (acid) is countable and can take (plural s)
Is that correct?Because I always thought that all liquids are noncountable
acid (n) = [uncountable and countable] a chemical substance that has a pH of less than 7.
Strong acids can burn holes in material or damage your skin:
thank you my dear friend
That was really usefull
