Methyl orange is an acid/base indicator changing from orange-yellow to red when pH lowers from 4.4 to 3.1, thus indicating the endpoint (pH ~ 4) of the 'bicarbonate (HCO3-) to carbonic acid (H2CO3)'-titration with dilute strong acid (HCl).

Which solution will turn methyl orange pink?

An acidic solution will turn methyl orange pink. Methyl orange is an acid-base indicator that changes color from red to yellow in acidic solutions and from yellow to pink in basic solutions.


How does methyl orange react with an acid?

Methyl orange is an acid-base indicator that changes color depending on the pH of the solution it is in. In an acidic solution, methyl orange appears red, while in a basic solution, it appears yellow. The reaction involves protonation of the indicator molecule in acidic conditions, leading to a color change.


What happens when methyl orange is added to sulphuric acid?

Methyl orange is a pH indicator that changes color in acidic and basic solutions. When added to sulfuric acid, which is a strong acid, the methyl orange changes color from yellow to red. This color change indicates that the solution is highly acidic.


What happens when nitric acid is mixed with methyl orange?

When nitric acid reacts with methyl orange, the color of the solution changes. Methyl orange is an indicator that changes color from orange/yellow in acidic solutions to red in basic solutions. In the presence of nitric acid, which is a strong acid, the solution would turn red.


What happens when methyl orange is added to sodium hydroxide?

When methyl orange is added to sodium hydroxide, the color of the solution changes from red (acidic) to yellow (basic). This indicates that the solution has become more alkaline due to the reaction between the sodium hydroxide and the indicator. Methyl orange is an acid-base indicator that changes color based on the pH of the solution.


What color would methyl orange be in milk of magnesia?

Methyl orange would be yellow when added to milk of magnesia, which is a white alkaline suspension.


What color does a mixture of phenolphthalein methyl orange and litmus have?

A mixture of phenolphthalein, methyl orange, and litmus would typically result in a color that depends on the pH of the solution. Phenolphthalein is colorless in acidic solutions and turns pink in basic solutions, while methyl orange is red in acidic conditions and yellow in neutral to basic conditions. Litmus is red in acidic solutions and blue in basic ones. Therefore, the overall color would vary, likely appearing red in acidic environments and transitioning through shades of orange to yellow in neutral to basic conditions, depending on the dominant indicator's pH response.


Is methyl acidic or basic?

Methyl is neither acidic nor basic. It is a neutral compound.


Which indicator gives us reddish pink color in acidic solution?

The red or pink color in an acidic solution is typically due to the presence of an acid-base indicator called phenolphthalein. In acidic conditions, phenolphthalein turns colorless, while in basic conditions it turns red or pink.


What is the solution of NaOH in methyl orange indicator?

The solution of NaOH in methyl orange indicator will turn from yellow to red. Methyl orange is an acid-base indicator that changes color in response to a change in pH. In the presence of a strong base like NaOH, the indicator will change to a red color indicating the basic nature of the solution.


What is Sodium salt of Methyl Orange?

Methyl orange is a slightly basic nitrogenous aromatic organic compound , its basic character is due to presence of lone pair of electron on nitrogen atom so it can't form the salt with sodium it forms a salt with strong acids.


How a mixture of methyl orange litmus and phenolphthalein could be used as a type of universal indicator?

A mixture of methyl orange, litmus, and phenolphthalein can be used as a universal indicator because each indicator covers a different pH range. Methyl orange turns red in acidic solutions, litmus turns red in acidic solutions and blue in basic solutions, and phenolphthalein turns pink in basic solutions. By observing the color change of the mixture, you can determine the approximate pH of the solution being tested.
