The Litmus solution becomes red when an acid is added in it.
which the solution will be acid
Acid turns it in red, while base will turn it blue.
A weak acid is a acid with a pH scale just below 7. The closer to seven the weaker an acid it is, a acid with a lower number is a stronger acid then an acid with a higher number. (no acids have a pH above 7)
The diluted solution has a slight hint of red as the other is just clear
Litmus paper is basically used to test nature of solution i.e acid or alkaline. For acid blue litmus turns to red. But for alkaline red litmus turns to blue color.
which the solution will be acid
A solution of phenol red is a liquid.
it becomes purple liquid

simple acid
Red cabbage or beetroot juice will do the job.
