Why methyl orange is used instead of phenolphthalein in hcl and naoh titration?

This is so since the pH at the end point of Phenolphthalein is 9.1 and methyl orange is 3.7. For a strong acid strong base titration which the end point is between 3-11 phenolphthalein is used

What turns different colors in acids and bases?
indicators - e.g methyl red, methyl orange, phenolphthalein etc.orThose substances are called indicators. They show different colours with different substances. Some common indicators are methyl orange, litmus, phenolphthalein etc.

orange
What is the mechanism of methyl orange in sodium carbonate and hydrogen chloride titration?
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.
Why methyl orange alkalinity equal to total alkalinity?
Alkalinity is different from basicity, which is directly related to the pH. The higher the pH, the more basic the water.Like acidity, there are different ways to measure and report alkalinity;The first is to titrate the water with acid titrant to the phenolphthalein end point. This is called the phenolphthalein alkalinity. Since phenolphthalein changes color at pH~8.3, this corresponds to a pH where all the CO32- present would be protonated.Second, acid titration to a methyl orange end point, pH~4.3, further converts the bicarbonate to aqueous carbon dioxide. At this end point, some of the weaker conjugate bases are protonated. The methyl orange end point titration indicates total alkalinity.
