Description : Why is CuSO4 more soluble in water than in organic solvent?
Last Answer : CuSO4 is ionic and water is polar. The types of bonding allowwater to dissolve the salt much more easily than an organic solvent(e.g. alcohol, hexane) could.
Description : Why is CuSO4 more soluble in water than in an organic solvent and why is the reverse true salicylic acid?
Last Answer : Water and copper sulfate are both polar compound; polar compounds are dissolved better in polar solvents. Salycilic acid is also polar but the solubility is lower because the benzene ring has a negative effect.
Description : Why is cuso4 the reverse true salicylic acid?
Last Answer : Feel Free to Answer
Description : How many atoms of sulphur are there in CuSO4?
Description : Why is salicylic acid the reverse of CuSO4?
Description : Is CuSO4 an ionic bond or covalent bond?
Last Answer : It is considered to be ionic.
Description : How many moles of water are associated with each mole of methane in methane hydrate?
Last Answer : 5.75 moles of water per mole of methane.
Description : How many atoms are there in CuSO4?
Last Answer : The answer depends on how many formula units of CuSO4 you have.In one formula unit, there are 6 atoms (1 Cu, + 1 S + 4 O).
Description : Which of the following expectorants acts both directly on the airway mucosa as well as reflexly ? (a) Potassium iodide (b) Guaiphenesin (c) Terpin hydrate (d) Bromhexine
Last Answer : Ans: A
Description : An aqueous solution of CuSO4 is acidic in nature because the salt undergoes (a) dialysis (b) hydrolysis (c) electrolysis (d) photolysis

Description : Copper substances when exposed to air gains a green coating due to the formation of: (1) CuO (2) CuCO3 Cu(OH)2 (3) CuSO4 (4) Cu(NO3)2
Last Answer : (2) CuCO3 Cu(OH)2 Explanation: When copper is exposed to air, it reacts with moist carbon dioxide in the air and slowly loses its shiny brown surface and gains a green coat. This green substance is ... Cu(OH)2). The formation of this green coating on the surface of a copper object corrodes it.
Description : Predict,what would happen if CuSO4 is stored in a zinc vessel?
Last Answer : Ans.No, as CuSO4 reacts with Zn.
Description : FeSO4 solution mixed with (NH4 ) 2 SO4 solution in 1 : 1 molar ratio gives the test of Fe2+ ion but CuSO4 solution mixed with aqueous ammonia in 1 : 4 molar ratio does not give the test of Cu2+ ion. Explain why ?
Last Answer : When FeSO4 and (NH4 ) 2 SO4 solution are mixed in 1 : 1 molar ratio, a double salt is formed. It has the formula FeSO4 (NH4 ) 2 SO4 . 6 H2O. In aqueous solution, the salt dissociates. When CuSO4 and NH3 are mixed in the molar ratio of 1 : 4 in solution, a complex [Cu (NH3 ) 4 ] SO4 is formed.

Description : Why the blue colour of CuSO4 turns colourless during electrolysis of CuSO4 solution by platinum electrode.
Last Answer : The platinum electrodes are inert. Hence does not dissolve into the solution. The Cu++ ions (blue) present in the solution are discharged on the surface of cathode & OH - are ... a result of this electrolysis, blue coloured CuSO4 solution is slowly converted into colorless H2SO4 solution.
