Question

Which is not a properly of a base? (A). Turn red litmus blue. (B). Reacts with acids to produce a salt and water (C). Feel slippery. (D). React with some metals to produce hydrogen gas

Answer 1

First, let's see which are the properties of the bases:

1. Aqueous solutions of bases are also electrolytes. Bases can be either strong or weak, just as acids can.

2. Bases often have a bitter taste and are found in foods less frequently than acids. Many bases, like soaps, are slippery to the touch.

3. Bases also change the color of indicators. Litmus turns blue in the presence of a base while phenolphthalein turns pink.

4. Bases do not react with metals in the way that acids do.

5. Bases react with acids to produce a salt and water.

Reviewing all the properties we can realize that the answer is D because bases do not react with metals as acids do.
