How do you determine whether an unknown substance is a carbonate or bicarbonate when comparing the mass of the substance before and after heating?
when bicarbonate is heated it decomposes into the carbonate, one water and one carbon dioxide. it is this loss of mass that will enable you to determine the identity of the anion in your unknown. make balanced equation. go moles to grams on each side using atomic mass then divide mass of carbonate by mass of bicarbonate.... aka product by reactant and if larger then 100 then it's a carbonate and subtract 100 from your answer and that is how much you gained... if smaller than multiply by 100% and then subtract your answer from 100 and that is how much you lost...

What is the implication of bicarbonate in soap making?
Sodium bicarbonate can be used as a neutralizing substance.
Is a sodium bicarbonate a mixture or a substance?
Sodium bicarbonate (NaHCO3) is a compound, not a mixture.
Is the element potassium the same as potassium carbonate?
No, potassium carbonate (K2CO3) is a substance often referred to as potash (though the term"potash" refer to other substances). It is a potassium compound. Bicarbonate of soda or baking soda is sodium bicarbonate or sodium hydrogen carbonate (NaHCO3). It is a sodium compound. Baking power is a mixture that contains sodium bicarbonate.
Is a bicarbonate ion an amphoteric substance?
Yes, a bicarbonate ion (HCO3-) is amphoteric because it can act as either an acid or a base depending on the reaction it is involved in. It can accept a proton to act as a base, forming carbonic acid (H2CO3), or it can donate a proton to act as an acid, forming carbonate ion (CO32-).
Is baking soda - NaHCO3 mixture or pure substance?
Sodium bicarbonate is a pure substance.
Is CO2 a carbonate?
No. A carbonate is a substance that contains either the carbonate ion or the bicarbonate ion.
What substance is responsible as the primary buffer in the blood?
carbonate-bicarbonate anions
What is a bicarbonate indicator?
A bicarbonate indicator is a substance that changes color in the presence of bicarbonate ions, like phenolphthalein or bromothymol blue. It is commonly used in titrations to determine the endpoint when bicarbonate ions are being neutralized.
Is bicarbonate an acidic or basic substance?
Bicarbonate is a basic substance.
Is a carbonate ion acid or alkali?
A carbonate ion is a weak base. It can act as a base by accepting a proton from water, forming bicarbonate ion and hydroxide ion in the process.
Is bicarbonate considered a basic or acidic substance in chemistry?
In chemistry, bicarbonate is considered a basic substance.
Is calcium carbonate a solid substance?
Yes, calcium carbonate is a solid substance.
What substance has the greatest number of elements from calcium carbonate sodium carbonate sodium bicarbonate magnesium sulfate calcium chloride sodium chloride ascorbic acid citric acid and sucrose.?
Sodium bicarbonate, with four elements: sodium, hydrogen, carbon, and oxygen. Calcium chloride has only two elements and the others listed have three elements each.
Is sodium bicarbonate a pure substance or mixture?
It is a pure substance as well as a compound
What is the substance that dissolves calcium carbonate?
Hydrochloric acid is the substance that dissolves calcium carbonate.
What is the main substance in limestone?
The main substance in limestone is calcium carbonate.
How can one determine the effusion rate of a substance"?
To determine the effusion rate of a substance, one can measure the time it takes for the substance to pass through a small opening or pore. By comparing this time to the effusion rate of a known substance under the same conditions, the effusion rate of the substance in question can be calculated.
