The volume of any material depends on the temperature; to prepare water solutions (titrant, standard solution, control sample, etc.) for chemical analysis the normal and general accepted temperature is 20 oC for water. Also volumetric glassware is graduated at 20 oC.

What property of a particular solute towards a solvent is necessary for recrystallization to occur?
The coolness of the solution causes recrystallization. This is because the solute becomes solid at a higher temperature than the solvent.

briefly discuss the errors tahat occur in the above titration and the change in the colour of the indicators.
Water serves as a medium or solvent in which other reactions occur and water is referred to as the universal solvent is that true or false?
True according to the text book "Fundamentals of Anatomy Physiology"

Does a solution settle over time?
no solutions don't settle but if you make supersaturated solution settling will occur

What of suspension mixtures?
Suspensions occur when a liquid has reached a total saturation point and can no longer dissolve a substance into the liquid. The solvent is then suspended in the solution
When does reverse osmosis occur?
Reverse Osmosis does not occur naturally. It works by using pressure to force a solution through a membrane, retaining the solute on one side and allowing the pure solvent to pass to the other side.
What is a solution composed of?
A solution is a mixture of two or more substances in the same physical state, especially where one substance is held in a different phase state within another. The substance which maintains its phase is the solvent, and the dissolved substance is the solute. the combination is a mixture because no chemical reactions occur between the substances. Gas phase solvents can only dissolve other gases. Liquid phase solvents can dissolve any of the three phases (solid, liquid, gas). Solids solvents can dissolve any of the three phases, but there are fewer instances in number (hydrogen or liquid mercury in metals, and alloys which are technically solutions). The solution form can have a different melting / freezing point than the separate elements or compounds.
What does not occur when a solid solute dissolves in a liquid solvent?
attractions between the solute and solvent particles remain static.
What is the difference between the hypotonic and hypertonic?
A hypertonic solution has more solutes than a cell, where the cell shrinks and possibly dies but a hypotonic solution, meanwhile, has less solutes than a cell where the cell expands and possibly bursts.
How can one fix runtime errors?
There exists a variety of reasons on why a runtime error might occur. The easiest solution to fix the majority of runtime errors you experience is to download software that cleans and fixes your registry.

The solute molecules mixed with the solvent molecules in a solution cause the of a solution to be higher than it is for an equal volume of pure solvent?
Raoult's Law and Vapor Pressure LoweringWhen a nonvolatile solute is added to a liquid to form a solution, the vapor pressure above that solution decreases. To understand why that might occur, let's analyze the vaporization process of the pure solvent then do the same for a solution. Liquid molecules at the surface of a liquid can escape to the gas phase when they have a sufficient amount of energy to break free of the liquid's intermolecular forces. That vaporization process is reversible. Gaseous molecules coming into contact with the surface of a liquid can be trapped by intermolecular forces in the liquid. Eventually the rate of escape will equal the rate of capture to establish a constant, equilibrium vapor pressure above the pure liquid.If we add a nonvolatile solute to that liquid, the amount of surface area available for the escaping solvent molecules is reduced because some of that area is occupied by solute particles. Therefore, the solvent molecules will have a lower probability to escape the solution than the pure solvent. That fact is reflected in the lower vapor pressure for a solution relative to the pure solvent. That statement is only true if the solvent is nonvolatile. If the solute has its own vapor pressure, then the vapor pressure of the solution may be greater than the vapor pressure of the solvent.Note that we did not need to identify the nature of the solvent or the solute (except for its lack of volatility) to derive that the vapor pressure should be lower for a solution relative to the pure solvent. That is what makes vapor pressure lowering a colligative property--it only depends on the number of dissolved solute particles.summarizes our discussion so far. On the surface of the pure solvent (shown on the left) there are more solvent molecules at the surface than in the right-hand solution flask. Therefore, it is more likely that solvent molecules escape into the gas phase on the left than on the right. Therefore, the solution should have a lower vapor pressure than the pure solvent.Figure %: The Vapor Pressure of a Solution is Lower than that of the Pure Solvent
