Carbon dioxide produced in respiration will cause hydrogencarbonate indicator to turn from a reddish colour to an orange/yellow.
It is actually not a specific test for carbon dioxide, relying on small pH changes due to carbonic acid, formed when carbon dioxide reacts with water
When carbon dioxide is bubbled through water, some of that carbon dioxide dissolves into the water. It then can react with the water to form carbonic acid. The formula for carbonic acid is H2CO3 (aq). Therefore, when carbon dioxide is bubbled through water, the solution becomes more acidic.
If a solution becomes more acidic and contains a pH indicator, the indicator changes colour to show the pH of the solution. With Universal Indicator, this change is from green, through yellow to orange. It does not go red as carbonic acid is quite weak.
if a solution has a normal concentration of carbondioxide then the hydrogencarbonate indicator is going to turn red but if the solutin gets acidic i.e concentration of carbondioxide increases then the indicator will turn yellow..
If the concentration of carbon dioxide in the indicator decreased, then the indicator would turn purple.
When there is a decreasing level of CO2 in the solution.
Adding dry ice to water a solution of carbonic acid is formed, the pH decrease and the color of indicator is changed.
Hydrogencarbonate indicator is a test for the amount of carbon dioxide in the air. It turns yellow with the presence of carbon dioxide.
Sodium hydrogen carbonate is used as an indicator of pH or as a test for the concentration of carbon dioxide. For the preparation of the solution see the link below.
hydrogen + carbonate + limewater = sodium hydrogenbicarbonaye
Hydrogen carbonate is a compound, not an element, and it therefore has a formula, not a symbol: H2CO3.
Sodium dihydrogen carbonate is not a proper chemical name and therefore has no formula, because carbonate anions have only two negative charges and therefore can not form a neutral compound with one sodium atom and two hydrogen atoms. The closest analogous compound is sodium hydrogen carbonate, which has the formula NaHCO3.

The hydrogen carbonate indicator is a dark, deep red, but then turns a brighter and richer colour red. :)
Sodium hydrogen carbonate is used as an indicator of pH or as a test for the concentration of carbon dioxide. For the preparation of the solution see the link below.

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.
Sodium hydrogen carbonate is a solid.
It's one of the diagnostics of whether body pH is being properly regulated. Please see the link.
A hydrogen carbonate ion has the formula HCO3- so the valency of a hydrogen carbonate ion is -1.
'Hydrogen Carbonate???? Do you mean Carbonic Acid . (H2CO3) or a Bi-carbonate such as sodium bi-carbonate. )NaHCO3)
Cesium hydrogen carbonate is CsHCO3
no
Sodium hydrogen carbonate is baking powder.
hydrogen carbonate is also known as baking soda or bicarbonate
