What else can I help you with?
What colour should sodium sulphate be in universal indicator?
Sodium sulfate is typically colorless in universal indicator. Universal indicator is a pH indicator that changes color based on the pH of a solution, and sodium sulfate is a neutral compound that does not significantly affect the pH.
What colour does universal indicator change to if carbonate acid is added?
Universal indicator changes to a color in the green/blue range when carbonate acid is added. This indicates a basic or alkaline pH level.
What colour is sodium hydroxide when you add universal indicator?
When you add universal indicator to sodium hydroxide, it will typically turn purple or dark blue in color, indicating that the solution is strongly alkaline.
Does sodium carbonate react with phenolphthalein indicator?
Sodium carbonate does react with phenolphthalein indicator, producing a color change from colorless to pink in alkaline solutions. Sodium carbonate is a common base that can be used to test for the presence of acidity or alkalinity in a solution using phenolphthalein.
What is colour of an aqueous solution of sodium carbonate in presence of a drop of phenolphthalein?
The color of an aqueous solution of sodium carbonate in the presence of phenolphthalein would be pink. Phenolphthalein turns pink in basic solutions with a pH above 8.2. Sodium carbonate is a basic compound that will cause the phenolphthalein indicator to change color to pink.
What colour should sodium sulphate be in universal indicator?
Sodium sulfate is typically colorless in universal indicator. Universal indicator is a pH indicator that changes color based on the pH of a solution, and sodium sulfate is a neutral compound that does not significantly affect the pH.
What colour does universal indicator change to if carbonate acid is added?

What colour is sodium hydroxide when you add universal indicator?
When you add universal indicator to sodium hydroxide, it will typically turn purple or dark blue in color, indicating that the solution is strongly alkaline.
What colour is sodium chloride in a universal indicator?
Sodium chloride is a neutral substance and will not exhibit a specific color in a universal indicator. Universal indicators change color based on the pH of a solution, not the presence of specific compounds like sodium chloride.
Does sodium carbonate react with phenolphthalein indicator?
Sodium carbonate does react with phenolphthalein indicator, producing a color change from colorless to pink in alkaline solutions. Sodium carbonate is a common base that can be used to test for the presence of acidity or alkalinity in a solution using phenolphthalein.
What does a sodium hydrogen carbonate indicator do?
A sodium hydrogen carbonate indicator is used to test for the presence of acids. It turns pink in the presence of an acid and yellow in the presence of a base. This color change helps to determine whether a solution is acidic or basic.
What is colour of an aqueous solution of sodium carbonate in presence of a drop of phenolphthalein?
The color of an aqueous solution of sodium carbonate in the presence of phenolphthalein would be pink. Phenolphthalein turns pink in basic solutions with a pH above 8.2. Sodium carbonate is a basic compound that will cause the phenolphthalein indicator to change color to pink.
What is the colour of sodium carbonate?
white
In the estimation of sodium carbonate you use methyl orange as an indicator?
Methyl orange changes color from red to yellow at a pH of around 4.4 to 3.1. In the titration process, the color change indicates the endpoint of the reaction between the sodium carbonate and the acid being used. This allows for precise determination of the amount of sodium carbonate present in the solution.
What color does base turn a universal indicator?
The color of a universal indicator in a basic solution is usually purple or blue.
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 does sodium hydroxide turn universal indicator blue?
When sodium hydroxide is added to universal indicator solution, it causes the indicator to turn blue because sodium hydroxide is a strong base. The blue color represents a high pH level, indicating that the solution has become more alkaline due to the presence of hydroxide ions released by the sodium hydroxide.
