acids wont change their color in methyl orange. bases changes the color when they are present in methyl orange.
HCl is white or no color in methyl orange.

Product depends on reaction conditions and quantity of sodium hydroxide used in the reaction. Initially sticky product [sodium salt of methyl salicylate] will form that on heating will effect saponification [hydrolysis of ester] resulting in sodium salicyale.

Methyl orange acts as a pH indicator in the process of sodium carbonate and hydrogen chloride titration. The addition of methyl orange will indicate the ratio of sodium carbonate to hydrogen chloride by the colour which develops.
yes .. we use methyl orange as an indicator ... when added it gives a straw yellow colour
Calcium sulphate + Sodium hydroxide > Sodium sulphate + Calcium hydroxide
Sodium hydroxide is a colourless liquid, and it is also called as caustic soda.

Methyl orange is an organic compound and might burn if heated sufficiently, though it's not especially flammable. Other than that, all of those are pretty much nonflammable.
It is a waxy-white.
