Why is the aquoues sodium carbonate solution added in?
Sodium carbonate is added in aqueous solution to provide a basic environment for reactions. It can help to neutralize acids present in the solution and adjust the pH to a desired level for certain chemical reactions to occur efficiently. Additionally, sodium carbonate can also act as a source of carbonate ions in reactions that require them.
Why is sulfuric acid added to the dilute bleach and iodide in the conical flask during titration of sodium hypochlorite with sodium thiosulphate?
Sulfuric acid is added to the bleach and iodide solution to acidify the solution and promote the reaction between hypochlorite and iodide to produce iodine. The iodine produced is then titrated with sodium thiosulfate to determine the concentration of hypochlorite in the sample. Acidifying the solution helps in stabilizing the generated iodine for a more accurate titration.
What kind of chlorine is in tap water?
Chlorine is typically added to tap water in the form of chlorine gas or sodium hypochlorite. Sodium hypochlorite, also known as household bleach, is the most common form used for water disinfection due to its stability and effectiveness at killing bacteria and viruses.
What is the reaction of sodium hypo chlorite in water?
When sodium hypochlorite is added in water it simply ionizes into Na+ and ClO-, if these ions react with water the products should be NaOH and HClO , but they again react as acid base and form the same ions in water.
Is chlorine in a pool a compound or mixture?
Chlorine in a pool is typically added in the form of a compound, usually in the form of sodium hypochlorite or calcium hypochlorite. These compounds dissolve in water to release chlorine ions, which help sanitize the pool water.

Is sodium bicarbonate a product or a reactant?
It depends. If sodium bicarbonate is added to something in a chemical reaction, then it is a reactant in this case. If a chemical reaction forms sodium bicarbonate, then it is a product.
When heat energy is added the speed of the molecules?
To hasten chemical reactions.
Is chlorine from the periodic table found in a pool?
Yes, chlorine from the periodic table is often used in pools as a disinfectant to kill bacteria and other harmful organisms. This chlorine is usually added in the form of chlorine compounds like sodium hypochlorite or calcium hypochlorite.
What happens when sodium carbonate and vinegar are added?
When sodium carbonate (washing soda) and vinegar are combined, a chemical reaction occurs, leading to the formation of carbon dioxide gas, water, and sodium acetate. The reaction is exothermic, meaning it releases heat. This reaction can be used for various purposes such as cleaning or as a demonstration of chemical reactions.
How does the law of the conservation of mass apply to to chemical reactions?
Atoms cannot be added or lost in a chemical reaction.
Displacement reaction of sodium and magnesium?
When sodium is added to a solution of magnesium chloride, a displacement reaction occurs where sodium displaces magnesium in the compound, forming sodium chloride and magnesium metal. The balanced chemical equation for this reaction is: 2Na(s) + MgCl2(aq) -> 2NaCl(aq) + Mg(s).
Sodium fizzes when added to water. But why doesn't sodium chloride fizz when added to water?
Sodium fizzes in water because it is undergoing a chemical reaction with water to form sodium hydroxide. The result is more stable than either of the original chemicals. When sodium chloride is added to water both of these substances are stable with respect to each other and no reaction occurs that results in a new chemical product.
