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...

Is a sodium bicarbonate a mixture or a substance?
Sodium bicarbonate (NaHCO3) is a compound, not a mixture.
What is the implication of bicarbonate in soap making?
Sodium bicarbonate can be used as a neutralizing substance.
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?
amphoteric
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
Is sodium bicarbonate a pure substance or mixture?
It is a pure substance as well as a compound
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 a sodium bicarbonate a mixture or a substance?
Sodium bicarbonate (NaHCO3) is a compound, not a mixture.
What is the implication of bicarbonate in soap making?
Sodium bicarbonate can be used as a neutralizing substance.
What substance can neutralize nitric acid?
Any base or alkali. However, carbonates also neutralise acids. So using sodium carbonate, or calcium carbonate , both very common substances. Na2CO3 + 2HNO3 = 2NaNO3 + H2O + CO2 or CaCO3 + 2HNO3 = Ca(NO3)2 + H2O + CO2
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?
amphoteric
What kind of substance is calcium carbonate?
calcium carbonate is really pointlees
Is baking soda - NaHCO3 mixture or pure substance?
Sodium bicarbonate is a pure substance.
What is baking soada made from?
Baking soda is a white crystalline powder (NaHCO 3 ) better known to chemists as sodium bicarbonate, bicarbonate of soda, sodium hydrogen carbonate, or sodium acid carbonate. It is classified as an acid salt, formed by combining an acid (carbonic) and a base (sodium hydroxide), and it reacts with other chemicals as a mild alkali. At temperatures above 300 degrees Fahrenheit (149 degrees Celsius), baking soda decomposes into sodium carbonate (a more stable substance), water, and carbon dioxide.
