FAQS on formula of methyl orange
Q: What is the chemical formula of methyl orange?
A: The chemical formula of methyl orange is C14H14N3NaO3S. It is an azo dye commonly used as a pH indicator. The sodium salt form ensures water solubility.
Q: How is the formula of methyl orange structured?
A: Methyl orange's structure includes a sulfonic acid group (-SO3Na) and a dimethylaniline moiety. The azo group (-N=N-) connects aromatic rings. Its formula reflects its ionic nature in solution.
Q: Is N-Methyl-2-pyrrolidone (NMP) related to methyl orange?
A: No, N-Methyl-2-pyrrolidone (NMP) has the formula C5H9NO, differing entirely from methyl orange. NMP is a polar solvent, whereas methyl orange is a pH-sensitive dye.
Q: What elements are present in methyl orange's formula?
A: Methyl orange contains carbon (C), hydrogen (H), nitrogen (N), sodium (Na), oxygen (O), and sulfur (S). The sodium comes from its sulfonate group. Azo groups contribute nitrogen atoms.
Q: Why does methyl orange have a sodium atom in its formula?
A: The sodium atom (Na) in methyl orange's formula neutralizes the sulfonic acid group (-SO3-). This ionic form enhances solubility in aqueous solutions. It stabilizes the compound for use in pH testing.
