Answer 2

Methyl orange indicator gives red color in acidic solution and yellow color in basic solution

Explanation:

Methyl orange is a indicator frequently used in chemical labs for titration because of its clear and distinct color change to yellow. Because it changes color at the pH of a mid strength acid, it is usually used in titration for acids.

Methyl orange does not have a full spectrum of color change, but has a sharper end point. Methyl orange shows red color in acidic medium and yellow color in basic medium. In a solution becoming less acidic, methyl orange moves from red to orange and finally to yellow with the reverse occurring for a solution increasing in acidity.

The entire color change occurs in acidic conditions an acid, it is reddish and in alkali, it is yellow. Methyl orange has a pKa of 3.47 in water at 25 °C (77 °F) . Direct contact with this chemical is dangerous as it contains mutating properties.
