What happens when copper II sulfate pentahydrate is heated equation?
(a) Solid copper(II) sulfate pentahydrate is gently heated. (i) Balanced equation: CuSO4•5H2O → CuSO4 + 5 H2O One point is earned for the reactant. Two points are earned for products.
What are the products of copper II sulfate pentahydrate when heated?
When copper(II) sulfate pentahydrate (CuSO4·5 H2O) is heated, it decomposes to the dehydrated form. The waters of hydration are released from the solid crystal and form water vapor. The hydrated form is medium blue, and the dehydrated solid is light blue.
What type of reaction is CuSO4 5H2O → CuSO4 5H2O?
Type of Reactions Lab Answers
|Reaction||Balanced Chemical Reaction||Type of Chemical Reaction|
|CuSO4(s) + H2O(l) → CuSO4*5H2O(s)||CuSO4(s) + 5H2O(l) → CuSO4*5H2O(s)||Synthesis|
|Ca(s) + S(s) → CaS(s)||Ca(s) + S(s) → CaS(s)||Synthesis|
|Mg(s) + O2(g) → MgO(s)||2Mg(s) + O2(g) → 2MgO(s)||Synthesis|
What is the formula for copper II sulfate pentahydrate?
Copper(II) sulfate pentahydrate/Formula
Why does CuSO4 turn white when heated?
When hydrated salt of copper sulphate is heated strongly, blue copper sulphate crystals turn white (due to the loss of water of crystallization). When anhydrous copper sulphate reacts again with water it will form Hydrated copper sulphate.
What happens when hydrated copper sulphate crystals are heated?
– When copper sulphate pentahydrate is heated, it loses water of crystallization as a result of evaporation. – Losing water of crystallization turns hydrated copper sulphate into anhydrous copper sulphate salt. On heating, blue coloured copper sulphate crystals become white.
What happens when copper sulphate crystals are heated?
When copper sulphate pentahydrate is heated, it loses water of crystallization as a result of evaporation. Losing water of crystallization turns hydrated copper sulphate into anhydrous copper sulphate salt. Heating turns crystals into anhydrous crystals which are colourless.
Why does copper II sulfate pentahydrate change color when heated?
When hydrate is heated, water molecules face a choice. When all the water is evaporated from hydrate, copper ions are left with only sulfate ions intheir surroundings. As a result, substance changes its color from blue to white.
What type of reaction is heating CuSO4 5H2O?
Problem: When copper(II) sulfate pentahydrate (CuSO4•5H2O) is heated, it decomposes to the dehydrated form. The waters of hydration are released from the solid crystal and form water vapor. The hydrated form is medium blue, and the dehydrated solid is light blue.
What is the balanced equation when aluminum reacts with copper II sulfate?
In this experiment, aluminum will be added to an aqueous solution of copper (II) sulfate in the presence of a catalyst (HCl). A single replacement reaction will take place, the products being aluminum sulfate and copper metal. The unbalanced equation for this reaction is: Al(s) + CuSO4(aq) → Al2(SO4)3(aq) + Cu(s).
What is the formula for copper II sulfate hydrate?
So copper (II) sulfate’s formula is CuSO 4, and the compound is neutral. The pentahydrate part of the name means the compound has five (penta) water molecules (hydrate). Therefore, the full formula is CuSO 4*5H 2O.
What is the formula for CuSO4?
The formula of the chemical compound Copper(II) sulfate is CuSO4
What happens when copper sulfate is added to water?
As stated above, copper sulfate accumulates as a heavy metal precipitate once it is applied to water. Because of this, it does not biodegrade. A buildup of copper sulfate can lead to a sterile water bottom, which can decrease and kill beneficial bacteria.
What is the molar mass of copper sulfate?
Copper(I) sulfate, also known as cuprous sulfate and dicopper sulfate, is the chemical compound with the chemical formula Cu2SO4 and a molar mass of 223.15 g mol−1. It is an unstable compound as copper(I) compounds are generally unstable and is more commonly found in the CuSO4 state.
