Answer 1

An acid
A neutral solution will not change the litmus paper colour or it will change to green
And a base would change it blue.

Answer 2

An acid solution.

Step-by-step explanation:

The litmus paper is an acid-base indicator, its colors change depending on the pH of the solution. If the pH < 4.5, the litmus paper turns red, if the pH> 8.3 the litmus paper turns blue.

If the pH > 7, there is a base solution, if the pH< 7 there is an acid solution, and if the pH = 7 its a neutral solution.

So, if the litmus paper turned red, the solution has pH<4.5, and it's an acid solution.
