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.
Which is more acidic nahco3 or na2co3?
NaHCO3 (sodium bicarbonate) is more acidic than Na2CO3 (sodium carbonate) because NaHCO3 can release more hydrogen ions when it dissolves in water due to the presence of the hydrogen carbonate ion. Na2CO3 contains the carbonate ion, which is a weaker base compared to the bicarbonate ion in NaHCO3.
The difference between ketones and carboxylic acids when reacting with sodium hydrogen carbonate?
The Difference between ketones and carboxylic acids when reacting with sodium hydrogen carbonate is that carboxlic acids give off caron dioxide when a sloution is added to little sodium hydrogen carbonate (or carbonate) solid or solution whereas ketone has no apparent reaction with the carbonate.
What is the chemical formula for cesium hydrogen carbonate?
The chemical formula for cesium hydrogen carbonate is CsHCO3.
How does sodium hydrogen carbonate neutralize acids in the blood?
Sodium hydrogen carbonate (baking soda) acts as a buffer in the blood by reacting with excess hydrogen ions from acids, forming water and carbon dioxide. This reaction helps to maintain the blood pH within a normal range by neutralizing the acidic substances.

What colour does litmus indicator turn when put in sodium hydrogen-carbonate?
When litmus indicator is put in sodium hydrogen-carbonate (a mild base), it turns blue. Sodium hydrogen-carbonate, also known as sodium bicarbonate, has a basic pH, which causes the blue color change in the litmus paper. In acidic solutions, litmus would turn red, but in this case, the basic nature of sodium hydrogen-carbonate results in a blue coloration.
How does hydrogen peroxide react with an egg shell?
Hydrogen peroxide reacts with the calcium carbonate in an eggshell, which is primarily composed of calcium carbonate (CaCO₃). When hydrogen peroxide is applied to the eggshell, it can break down the calcium carbonate, releasing carbon dioxide gas and forming calcium hydroxide. This reaction can cause the eggshell to bubble and dissolve over time, demonstrating the acidic nature of hydrogen peroxide in contrast to the alkaline properties of calcium carbonate.
Why is sodium hydrogen carbonate used as a treatment for ant stings?
Sodium hydrogen carbonate, or baking soda, can help neutralize the venom from ant stings, reducing pain and inflammation. Its alkaline nature can help counteract the acidic venom injected by ants, providing relief from the sting.
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.
How does sodium hydrogen carbonate neutralize acids in the blood?

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.
Why is sodium hydrogen carbonate important in cooking?
Sodium hydrogen carbonate, also known as baking soda, is important in cooking because it reacts with acidic ingredients to produce carbon dioxide gas, which helps baked goods rise and become light and fluffy. It can also be used as a leavening agent in recipes that do not contain any acidic ingredients. Additionally, it helps neutralize overly acidic flavors in dishes.
How can calculate equivalent weight of calcium carbonate?
The equivalent weight of calcium carbonate can be calculated by dividing its molecular weight by the number of acidic hydrogen ions that it can donate in a reaction. In the case of calcium carbonate, it can donate two moles of hydrogen ions, so the equivalent weight would be its molecular weight divided by 2.
