In chemistry, solvent effects are the influence of a solvent on chemical reactivity or molecular associations. Solvents can have an effect on solubility, stability and reaction rates and choosing the appropriate solvent allows for thermodynamic and kinetic control over a chemical reaction. A solute dissolves in a solvent when solvent-solute interactions are more favorable than solute-solute interaction. WebIt appears a spot runs about 1/2 way up the plate.
