Which description is not a property of an acid? turns litmus paper red bitter taste corrosive dissolves metals

If you've ever tried a lemon, you would have realised that it wasn't bitter. Lemons also happen to have a low PH, making them an acid.
If the properties of lemons are anywhere close to other acids (hint: they are), then the answer should be evident.

The description that is not a property of an acid is: Bitter taste.                     Acids have a sharp taste. Hope this helps.
