Answer 1

3rd statement about this acidic reaction is not true

In acidic reactions,  Litmus paper is available in red and blue varieties and is typically more trustworthy. To determine whether a solution is normal or acidic, use litmus paper. The acid or basic strength is not precisely outlined in Litmus's paper. Thus, Base causes red litmus to turn blue.

The pH scale has numbers 0 through 14. Seven is the neutral pH. Over 7 is a base, and anything below 7 is acidic.

H+ ions are present in all acidic reactions. As a result, whether mineral or organic, all acid solutions transmit electricity. They allow an electric current to flow through them.
