Excessive quantities of wash water are added to the calcium oxalate and water precipitate how does this affect the mass?
Adding excessive quantities of wash water to the calcium oxalate and water precipitate might result in the loss of some of the precipitate during filtration due to increased solubility. This could lead to an underestimate of the mass of calcium oxalate obtained in the experiment.
Could you prepare oxalic acid by adding hcl to a solution og sodium oxalate?
Yes, oxalic acid can be prepared by adding hydrochloric acid (HCl) to a solution of sodium oxalate. The reaction that occurs is double displacement reaction where sodium chloride and oxalic acid are formed. Oxalic acid can be obtained by precipitating it out of the solution by adjusting the pH.
Is adding of calcium to water a chemical change?
Adding calcium to water is a physical change because it does not alter the chemical composition of either the calcium or water molecules. The calcium simply dissolves in the water to form calcium ions and does not undergo a chemical reaction.
What is the role of adding calcium chloride to the saliva?
Adding calcium chloride to saliva can help initiate coagulation reactions in forensic analysis, aiding in DNA extraction from biological samples such as blood or saliva. The calcium ions released from calcium chloride can neutralize the charge on DNA molecules, promoting their precipitation and separation from other cellular components.
What is purpose of adding HCl to the CaCO3 -H2O mixture prior to dilute?
Adding HCl to the CaCO3 - H2O mixture prior to dilution helps dissolve the calcium carbonate by reacting with it to form calcium chloride, water, and carbon dioxide. This step is done to increase the solubility of calcium carbonate and facilitate its removal in subsequent steps.

What is the purpose of adding calcium carbonate after removal of casein?
acts as a drying agent
What is the purpose of adding calcium carbonate after removal of the casein?
Adding calcium carbonate after the removal of casein helps to increase the pH of the solution. This is important for the precipitation and separation of unwanted impurities from the liquid. It also aids in the formation of a solid precipitate, which can be easily separated from the liquid.
What product can be made by adding water to calcium oxide?
calcium hydroxide is formed.
When is it safe to swim after adding calcium to pool?
Any time you like calcium is harmless

Is adding calcium to water a chemical property or chemical change?
Calcium reacting with water is a chemical change.
What is purpose of adding HCl to the CaCO3 -H2O mixture prior to dilute?
Adding HCl to the CaCO3 - H2O mixture prior to dilution helps dissolve the calcium carbonate by reacting with it to form calcium chloride, water, and carbon dioxide. This step is done to increase the solubility of calcium carbonate and facilitate its removal in subsequent steps.
Is adding calcium to water a mixture or a compound?
When you add calcium to water, it forms calcium ions (Ca2+) in the water. This results in a mixture of calcium ions in water. The calcium ions and water molecules remain separate entities rather than bonding to form a compound.
How does on lime a lake?
by adding calcium carbonate to raise the pH level.
