Description : (a) Show on a diagram the transfer of electrons between the atoms in the formation of MgO. Write symbols of cation and anion present in MgO. (b) Name the solvent in which ionic compounds are generally soluble. (c) Why are aqueous solutions of ionic compounds able to conduct electricity? -Chemistry
Last Answer : (b) Ionic compounds are soluble in water. (c) It is because aqueous solutions consist of ions which can move freely in them and carry current.
Description : What is solvent called soluble ?
Last Answer : The solvent that is dissolved is called solvent.
Description : When an organic compound is present in aqueous medium and is less soluble in any organic solvent, then it is separated by `:`
Last Answer : When an organic compound is present in aqueous medium and is less soluble in any organic ... B. distillation C. chromatography D. sublimation
Description : Is RbOH soluble in non polar solvent?
Last Answer : It is not soluble in nonpolar solvents.
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 : Lipids have the following properties: (A) Insoluble in water and soluble in fat solvent (B) High energy content (C) Structural component of cell membrane (D) All of these
Last Answer : Answer : D
Description : Thermosetting materials (A) Are cross-linked molecules (B) Soften on application of heat (C) Are solvent soluble (D) None of these
Last Answer : (A) Are cross-linked molecules
Description : Pick out the wrong statement regarding the solubility characteristics of high polymers. (A) Greater the degree of cross-linking in the polymer, lesser is its solubility (B) Polymers having more ... of the solvent (D) High molecular weight polymers on dissolving gives solution of very low viscosity
Last Answer : (D) High molecular weight polymers on dissolving gives solution of very low viscosity
Description : Pick out the wrong statement. (A) Cellulose acetate membranes are used in dialysis process (B) Elutriation process refers to when the soluble material is largely concentrated on the surface of an ... that various streamflow from one to another (D) Zirconia probe is used for the humidity measurement
Last Answer : (D) Zirconia probe is used for the humidity measurement
Description : In a liquid-liquid extraction, 10 kg of a solution containing 2 kg of solute C and 8 kg of solvent A is brought into contact with 10 kg of solvent B. Solvent A and B are completely immiscible in each other whereas ... (C) Less than 1 kg of C is transferred to B (D) No amount of C is transferred to B
Last Answer : (A) The entire amount of C is transferred to solvent B
Description : The operation involved when the soluble material is largely on the surface of an insoluble solid and is merely washed off by the solvent is called (A) Decoction (B) Percolation (C) Elutriation or elution (D) None of these
Last Answer : (C) Elutriation or elution

Last Answer : carbon tetrachloride
Description : What would happen to the cells if the fatty acids in the membrane became soluble in water?
Last Answer : it would cause the cell to lose all of its contents to theoutside
