When you add methyl red to a solution it will indicate it's pH. When the pH is under 4.4 the solution will appear red in color (or maybe pink). When the solution is above pH 6.2 it will appear yellow in color. Any where in between will appear orange. So if you add base to a red/pink or orange solution it will turn yellow as the solution becomes more basic. But I honestly do not know th actual chemical reaction that causes the indictor's color change.

What is the reactions of hydrochloric acid to methyl orange?
it changes into red colour
When you add an acid to an alkali it changes to a neutral which colour change would this show with an indicator?
It depends on the indicator and there are quite a few. Methyl Red, Methyl orange and Phenolphthalein are 3 such acid-base indicators. If phenolphthalein is used as the indicator and added to the base it would immediately turn red/pink. As acid is titrated in, the red/pink will disappear and go colorless.
What is the name of a chemical which changes colour when it is mixed with acids or alkali's?
If you want the general term, it's "indicator". If you want a specific one ... methyl red, litmus, or bromothymol blue are some examples (there are lots of others).
If red litmus is added to a alkali?
When red litmus is added to an alkali, its colour changes to blue. This is because an alkali is a base and has the property of turning red litmus paper or red litmus solution to blue.
If soda water or any indicator which will change into the colour of red?
Methyl Orange is red in an acidic solution.
