What is the effect of acetic acid on methyl orange?
Here, the solution of the acetic acid and methyl orange makes for a weak acid. If we represent it as Hln, then its dissociation at equilibrium will…
What is the effect of hydrochloric acid on methyl orange?
Methyl orange indicator turns reddish pink because of the action of dilute HCl. Methyl orange turn pink coloured in acidic solutions and yellow coloured in basic solutions.
What is the effect of Sulphuric acid on methyl orange?
sulphuric acid in methyl orange then it changes its colour from orange to red. 2. If we add few drops of dil. sulphuric acid in phenolpthalien then the solution will become colourless.
Is methyl orange basic or acidic?
Methyl Orange is a weak acid which dissociates in water forming orange neutral molecules. Under acidic conditions, the equilibrium is to the left, and the concentration of the neutral molecules is too low for the orange colour to be observed.
What is the effect of adding dilute nitric acid to methyl orange?
Nitric acid turns it from orange to pink.
When methyl orange is mixed with citric acid lemon juice It turns?
a) Methyl orange change to red in colour in presence of acid. Lemon juice is acidic in nature.
What happens when phenolphthalein is added to acid?
Phenolphthalein is often used as an indicator in acid–base titrations. For this application, it turns colorless in acidic solutions and pink in basic solutions. Phenolphthalein changes colour sharply at about pH 8. For most purposes, this means that it is pink in alkaline solutions and colourless in acidic solutions.
What is the effect of nitric acid on phenolphthalein?
It turns colorless in acidic solution and pink in alkaline solution. Therefore, nitric acid is a very strong acid. Under strong acid conditions, phenolphthalein is orange. When nitric acid is added to water, many hydronium ions are formed and the reaction is exothermic in nature.
