Is the dissolving of sodium thiosulfate in water endothermic or exothermic reaction?
The dissolving of sodium thiosulfate in water is an exothermic reaction. This means that heat is released during the process as the sodium thiosulfate molecules form bonds with water molecules.
What kind of chemical reaction do you get when you heat copper sulfate pentahydrate?
Heating copper sulfate pentahydrate leads to a dehydration reaction, where water molecules are removed from the compound. This results in the formation of anhydrous copper sulfate.
What is the balanced equation when copper ll sulfate pentahydrate is heated?
The balanced equation for the heating of copper(II) sulfate pentahydrate (CuSO4•5H2O) is: CuSO4•5H2O(s) -> CuSO4(s) + 5H2O(g). This reaction decomposes the pentahydrate compound into anhydrous copper(II) sulfate and water vapor.
The amount of heat needed to melt one kilogram of a substance?
The amount of heat required to melt one kilogram of a substance is known as the heat of fusion or the latent heat of fusion. It represents the energy needed to change a solid into a liquid at its melting point without a change in temperature.
Why did the supersaturated solution begin to drop small crystals when the additional sodium thiosulfate was added?
The supersaturated solution begin to drop small crystals when the additional sodium thiosulfate was added because the supersaturated solution got reverted back to a saturated solution. Every solution has it;s own level of saturation, at a certain temperature a limit of the solute can be disolved in it, if you heat the solution the limit changes and more of the solute can be added in the solution. This is a supersaturated solution.When you drop an extra crystal into a supersaturated solution, all the extra crystals that aren't suppose to be in it crystalize out of the solution.
Is the dissolving of sodium thiosulfate in water endothermic or exothermic reaction?
The dissolving of sodium thiosulfate in water is an exothermic reaction. This means that heat is released during the process as the sodium thiosulfate molecules form bonds with water molecules.
Why does water go cold when you add sodium thiosulfate crystals to it?
Adding sodium thiosulfate crystals to water causes an endothermic reaction, meaning it absorbs heat from the surrounding environment. As a result, the water temperature decreases, making it go cold.
What is sodium thiosulfate used for in commercial applications?
Sodium thiosulphate is used commercially in many products, including bleah, disinfectants, table salts, cleaning products and heat production in heat packs and hand walmers.
What is another name for heat of fusion?
Another name for heat of fusion is enthalpy of fusion.
Does boron conduct heat?
The main use of boron compounds is in the form of sodium tetraborate pentahydrate (Na2B4O7) for making insulating fiberglass and sodium perborate bleach. Wikipedia says its an excellent insulator so am afraid it cant conduct heat :)
Heating copper II sulfate pentahydrate?
To heat copper II sulfate pentahydrate, you would need to apply heat gradually to remove the water molecules bound in the crystal structure. As you heat it, the pentahydrate will lose its water molecules and eventually transform into anhydrous copper II sulfate, which is a white powder. It's essential to heat it gently to prevent decomposition or spattering.
What is a balanced equation for the decomposition of copper sulfate pentahydrate?
CuSO4•5H2O + heat ---> CuSO4 + 5H2O
The amount of heat necessary to change 1 kg of a solid into a liquid at the same temperature is called the?
molar heat of fusion
What is the definition of heat fusion?
heat fusion is to join things together by heat. ie plastic welding.
How do you prepare Benedicts reagent?
To prepare Benedict's reagent, dissolve 17.3 g of sodium citrate and 1.72 g of anhydrous sodium carbonate in distilled water. Then add 0.5 g of copper sulfate pentahydrate and heat the solution until the salts dissolve completely. Adjust the volume to 1 L with distilled water, filter the solution if needed, and store in a cool, dark place.
The amount of energy needed to change a material from a solid to a liquid is the heat of what?
The latent heat of evaporation
What is the energy required to go from a solid to a liquid called?
The latent heat of fusion
