What is the colour of hydrogen carbonate indicator?
The hydrogen carbonate indicator changes color from red in acidic conditions to yellow in neutral conditions to purple in basic conditions.
What happens when carbon dioxide is bubbled into hydrogen carbonate indicator?
When carbon dioxide is bubbled into a hydrogen carbonate indicator, the indicator solution will turn yellow. This is due to the formation of carbonic acid, which is a weak acid. The carbon dioxide reacts with water in the indicator solution to form carbonic acid, causing the color change.
What is the mechanism of methyl orange in sodium carbonate and hydrogen chloride titration?
In the presence of sodium carbonate (base) and hydrogen chloride (acid) in a titration, methyl orange indicator changes color at the endpoint. At the beginning of the titration, the solution is basic due to the sodium carbonate, causing the methyl orange to appear yellow. As the acid is added and the solution becomes more acidic, the indicator changes to red at the endpoint when all the base has been neutralized by the acid.
What is the chemical formula for cesium hydrogen carbonate?
The chemical formula for cesium hydrogen carbonate is CsHCO3.
Is hydrogen carbonate soluble?
Yes, hydrogen carbonate (bicarbonate) is soluble in water. It dissolves readily to form a solution.

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.

Does hydrogen carbonate indicator shows any color with oxygen?
No, hydrogen carbonate indicator does not change color when exposed to oxygen. It is mainly used to detect the presence of carbon dioxide, as it turns pink in the presence of an acid (carbon dioxide dissolved in water forms carbonic acid).
Symbol for hydrogen carbonate?
Hydrogen carbonate is a compound, not an element, and it therefore has a formula, not a symbol: H2CO3.
What is the chemical formula for cesium hydrogen carbonate?
The chemical formula for cesium hydrogen carbonate is CsHCO3.
Is hydrogen carbonate soluble?
Yes, hydrogen carbonate (bicarbonate) is soluble in water. It dissolves readily to form a solution.
Is sodium hydrogen carbonate is metal carbonate?
no
Is sodium hydrogen carbonate a weaker base than sodium carbonate?
Yes, sodium hydrogen carbonate (baking soda) is a weaker base than sodium carbonate. This is because sodium hydrogen carbonate is a less effective proton acceptor compared to sodium carbonate.
What is the hydrogen carbonate ion formula?
The hydrogen carbonate ion has the formula HCO3-.
Why is sodium hydrogen carbonate in baking powder?
Sodium hydrogen carbonate is baking powder.
