Methyl orange cannot be used as indicator if `…………`

A transistor cannot be used as an

Statement: In an acid-basic titration involving a strong base and a weak acid, methyl orange can be used as an indicator. Explanation: Methyl orange changes its colour in the pH range 3 to 5.

Magnets cannot be made using

In the study of titration of NaOH and Na_(2)CO_(3) . NaOH and NaHCO_(3) , Na_(2)CO_(3) and NaHCO_(3) , phenophthalein and methyl orange are used as indicators. (a). When phenolphthalein is used as an indicator for the above mixture: (i). It indicates complete neutralisation of NaOH or KOH (ii). It indicates half neutralisation of Na_(2)CO_(3) because NaHCO_(3) is formed at the end point. (b). When methyl orange is used as an indicator for the above mixture (i). It indicates complete neutralisation of NaOH or KOH (ii). It indicates half neutralisation of Na_(2)CO_(3) because NaCl is formed at the end point. Q. A 10 g moxture of NaHCO_(3) and KOH is dissolved in water to make 1000 mL solution. 100 " mL of " this solution required 50 " mL of " 0.2 M HCl for complete neutralisation in the presence of phenolphthalein as indicator What is the percentage of NaHCO_(3) in the mixture?

Q. 1 L solution of Na_(2)CO_(3) and NaOH was made in H_(2)O . 100 " mL of " this solution required 20 " mL of " 0.4 M HCl in the presence of phenolphthalein however, another 100 mL sample of the same solution required 25 " mL of " the same acid in the presence of methyl orange as indicator. What is the molar ratio of Na_(2)CO_(3) and NaOH in the original mixture.

A mixture NaOH+Na_(2)CO_(3) required 25mL of 0.1 M HCl using phenolpththalein as the indicator. However, the same amount of the mixture required 30mL of 0.1M HCl when methyl orange was used as the indicator. The molar ration of NaOH and Na_(2)CO_(3) in the mixture was:

A 100 ml mixture of Na_(2)CO_(3) and NaHCO_(3) is tittrated against 1 M HCl. If v_(1)L and v_(2)L are consumed when phenolphthalein and methyl orange are used as indicators respectively in two separate titrations, which of the following is true form molarities in the original solution.

Methyl orange (an acid-base indicator) can be prepared by following sequence of reactions What would be the structure of methyl orange?
