2.5 Celsius
What is the molar mass of haemocyanin and the freezing point of the solution when an aqueous solution is prepared by dissolving 1.5 grams of haemocyanin a protein obtained from crabs in 0.25 litres of?
Haemocyanins are a group of proteins.
Does cyclohexane and hexane form a solution?
Propane, being a GAS but an aliphatic hydrocarbon is soluble in cyclohexane, which is a liquid and a cycloaliphatic hydrocarbon. .
When the dissolving rate equals the rates at which molecules come out of solution the solution is in?
When the dissolving rate equals the rate at which molecules comes out of solution the solution is in 'equilibrium'.
How do eliminate biphenyl as a by product in a Grignard reaction?
Biphenyl will be dissolved in ether along with your desired product after Grignard synthesis. If you add an aqueous sodium hydroxide (NaOH) solution to this it will react with your desired product but not the biphenyl and form two layers of solution. One layer will be biphenyl dissovled in ether the other will be NaX (where X is your desired product, just with the Na attached to an oxygen rather than a H) dissolved in water. The latter solution can be separated with a separatory funnel; it will be the lower layer. To precipitate you product from its aqueous solution just cool it and add hydrochloric acid (HCl). There you have it, that's how to eliminate byphenyl from your desired product. Hope it helped.

When a solute is dissolved in a solvent the solvents?
boiling point decreases and its freezing point increases No, other way round. That's why you put antifreeze in vehicle radiators. It makes the water less likely to freeze.

What is a substance that does the dissolving in a solution?
It is a solvent that dissolves in a solution.

Why does dissolving take place?
Dissolving takes place to turn a mechanical (heterogeneous) mixture into a solution (homogeneous solution).
What is the term for dissolving medium in the solution?
Solvent is the term for a dissolving medium in a solution. The material which is being dissolved is called the solute.
What is weak solution?
the solution which has low dissolving power i guess
In a solution what is the substance doing the dissolving?
It is a solvent that dissolves in a solution.
