Methyl Orange

"Methyl orange is a pH indicator frequently used in titrations."

"It is often used in titrations because of its clear and distinct colour change. Because it changes colour at the pH of a mid-strength acid, it is usually used in titrations for acids. Unlike a universal indicator, methyl orange does not have a full spectrum of colour change, but has a sharper end point."

"Methyl orange has mutagenic properties."
