What was done in the experiment to ensurethat all KHCO3 was react?
In the experiment, excess HCl was added to ensure that all KHCO3 was reacted. Excess reactants ensure that all of the limiting reactant is completely consumed in the reaction, leaving none unreacted. When all KHCO3 reacts, the reaction reaches completion.
What is in souble?
It seems like there might be a typo in your question. If you're asking about "souble," it could refer to "double," but without additional context, it's unclear. If you meant "soluble," it refers to a substance's ability to dissolve in a solvent, typically water. Please clarify if you meant something else!
Why is the mass of KCl recovered less than the starting mass of KHCO3?
The mass of KCl recovered is less than the starting mass of KHCO3 because during the reaction that converts KHCO3 to KCl, carbon dioxide (CO2) and water (H2O) are released as byproducts. This loss of gas and water contributes to the decrease in mass. Additionally, any experimental losses during the transfer or handling of materials can further reduce the recovered mass of KCl.
Why is the mass of kcl recovered less than the stating mass of KHCO3?
The mass of KCl recovered is less than the starting mass of KHCO3 due to the loss of carbon dioxide (CO2) and water (H2O) during the reaction. When KHCO3 decomposes, it releases these gases, which are not captured, leading to a reduction in the total mass. Additionally, some potassium ions may remain in solution or be lost during handling, contributing further to the mass discrepancy.
Is AgC2H3O2 souble or insoluble in water?
Silver acetate (AgC2H3O2) is slightly soluble in water. It can dissolve to a small extent, but it is considered insoluble for practical purposes because only a small amount dissolves.
What does souble meen?
souble means that it can dissolve into another substance
What is the equation for reacting KHCO3 with H2O?
Khco3+h2o
Formula for potassium bicarbonate?
First off, it's POTASSIUM. (K) The formula would be: KHCO3
What is the chemical formula for potassium hydrocarbonate?
More commonly known as potassium bicarbonate KHCO3
What was done in the experiment to ensure that all KHCO3 was react?
In the experiment, excess HCl was added to the solution containing KHCO3. This ensured that all of the KHCO3 would react completely, as any unreacted KHCO3 would still be neutralized by the excess HCl.
Why is the mass of KCL recovered less the starting mass of KHCO3?
The mass of KCl recovered is less than the starting mass of KHCO3 because during the chemical reaction between KHCO3 and HCl to form KCl, CO2 gas is evolved. Some of the starting mass of KHCO3 is lost as gas during the reaction, leading to a lower mass of the end product (KCl) compared to the original mass of KHCO3.
Is khco3 soluble?
Yes, potassium bicarbonate (KHCO3) is soluble in water. It dissolves readily to form a clear solution.
The maximum number of grams of potassium that can be obtained from 100 grams of KHCO3 is?
The molar mass of KHCO3 is 100.12 g/mol. This means that 100 grams of KHCO3 contains 39.1 grams of potassium (K) ions.
Is sand souble in cold water were is it?
Sand will not dissolve in water.
What salt is KHCO3?
Potassium hydrogencarbonate
What is the formula of hydrogen carbonates?
It is KHCO3
Why should the moles of KHCO3 AND THE MOLES OF KCL PRODUCED BE THE SAME?
The moles of KHCO3 and KCl produced should be the same because they are stoichiometrically related in the chemical reaction that produces them. For every mole of KHCO3 that reacts, it produces one mole of KCl. This means that the number of moles of KHCO3 consumed is equal to the number of moles of KCl produced in the reaction.
