What else can I help you with?
What will happen if heat crystals of CuSO4 pentahydrate in a test tube and note the water given off allow to cool and compare the color of anhydrous CuSO4 with original crystals?
Heating crystals of CuSO4 pentahydrate in a test tube will cause the water molecules trapped in the crystal lattice to evaporate, leaving behind anhydrous CuSO4 crystals. The color change observed will be from blue (for the hydrated form) to white (for the anhydrous form).
What can you get from evaporating copper sulphate?
Evaporating a copper sulphate solution you can obtain anhydrous crystals of CuSO4. Increasing the temperature CuSO4 will be thermally dissociated.
How do you separate hydrated CuSO4 from its aqueous solution?
One common method to separate hydrated CuSO4 from its aqueous solution is through the process of evaporation. By heating the solution, water evaporates leaving behind solid CuSO4. The solid can then be filtered to separate it from the remaining liquid.
What is cuso4 aqueous colour?
NO such formula as ' cuso4 ' . If you mean ' Copper sulphate' then the formula is ' CuSO4 ' NOTE the use of capital letters. See my note below!!!!! The colour of aqueous CuSO4 is BLUE. NB When writing chemical formula. #1 Single letter elemental symbols are ALWAYS a CAPITAL letter. #2 Double letter elemental symbols are first letter is a capital letter, and the second letter is small/lower case. This is the International recognised symbolism and as shown in the Periodic Table. It is done to avoid confusion!!! ' CO ' is carbon monoxide ' Co' is cobalt. Hence Copper is 'Cu' NOT 'cu' Sulphur is 'S' NOT 's' Oxygen is 'O' NOT 'o'.
When cuso4 5h2o is heated in a crucible there is a loss of water hw should a student determine the amount of water lost?
To determine the amount of water lost when heating CuSO4·5H2O in a crucible, a student should first weigh the crucible with the hydrated copper(II) sulfate before heating. After heating, the student should allow the crucible to cool and then weigh it again. The difference in mass between the initial weight and the final weight will give the mass of water lost during the heating process. This method provides a direct measurement of the water loss through the dehydration of the compound.

Why blue crystals of copper sulphate on heating turn colourless?
The formula of the blue crystals of copper sulphate is CuSO4.5H2O. When they are heated mildly, the water from the crystals evaporate, giving just CuSO4. This 'anhydrous' form of copper (II) sulphate is white in colour.
What is the formula of copper (II) sulfate?
The formula unit for copper II sulfate is CuSO4.
What is the value of x if mass of CuSO4.xH2O and mass of CuSO4 is given after heated?
The value of x can be determined by comparing the masses of CuSO4.xH2O and CuSO4 before and after heating. By calculating the difference in mass, the value of x can be obtained based on the loss of water molecules during the heating process.
What is the formula for copper sulfate crystals How much water do the 'home grown' crystals contain?
Well the formula is CuSO4
What mass of anhydrous copper 2 sulfate can be obtained by heating 125g of cuper 2 sulfate pentahydrate?
To find the mass of anhydrous copper(II) sulfate obtained: Calculate the molar mass of each compound: CuSO4·5H2O (pentahydrate) and CuSO4 (anhydrous). Use the molar ratio between CuSO4 and CuSO4·5H2O to find the amount of anhydrous CuSO4. Convert the amount to mass using the molar mass of CuSO4. The mass of anhydrous CuSO4 will be less than the initial 125g due to the loss of water upon heating.
What colour change of the substance after a heat strongly a few crystals of blue vitriol copper 2 sulphate in a dry test tube?
The blue copper(II) sulfate is a pentahydrate: CuSO4.5H2O. The anhydrous form - CuSO4 - is white.
What can you get from evaporating copper sulphate?
Evaporating a copper sulphate solution you can obtain anhydrous crystals of CuSO4. Increasing the temperature CuSO4 will be thermally dissociated.
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.
What are the colours of cuso4.6h2o?
The compound CuSO4·6H2O, known as copper(II) sulfate pentahydrate, appears as blue crystals.
How do you separate hydrated CuSO4 from its aqueous solution?
One common method to separate hydrated CuSO4 from its aqueous solution is through the process of evaporation. By heating the solution, water evaporates leaving behind solid CuSO4. The solid can then be filtered to separate it from the remaining liquid.
A symbol equation for the thermal decomposition of copper sulfate?
CuCO3 --> CO2 + CuO (gas + black powder) Further heating may result in : CuO --> 2Cu + O2 (metal copper + gas)
