yes .. we use methyl orange as an indicator ... when added it gives a straw yellow colour
What color is methyl orange when hydrochloric acid is added?
The effect of dilute HCl on the colors of the methyl orange will most likely be red. This is assumed because of both most likely having a pH of 3.1, which will end up red.
What is the colour of methyl red when added to an acid?
Methyl red turns red in acidic solutions (under pH 4.4), yellow in alkaline solutions (pH over 6.2),and is orange in between.
What happens when dilute sulphuric acid is added to copper oxide?
CuO + H2SO4 -> CuSO4 + H2O copper sulfate and water produced
When dilute sulphuric acid is added to zinc granules the gas produced is?
When sulphuric acid is added to zinc granules , the gas produced is hydrogen gas. Zinc displaces hydrogen from sulphuric acid.

What is the chemical formula for methyl orange?
Methyl orange is synthesized by reaction of sulfanilic acid, sodium nitrite, and dimethylaniline. First, sulfanilic acid is dissolved in dilute aqueous acid. Sodium nitrite is added to produce a disowning salt .Chemical formula of Methyl Orange: C14H14N3NaO3S
