Do oil and vinegar have different densities?
The density is the amount of mass per unit volume. The density depends on what kind of liquid it is, and a smaller amount on the temperature and pressure. Oils are the least dense of the three you mention. In general, dissolving stuff in water makes it more dense, making vinegar the densest of the three.
What are the 3 ways to dissolve a solute in a solvent?
There are three ways to make solids dissolve faster: Break the solute into smaller pieces. Stir the mixture. * Heat the mixture.
What are 3 ways to get something to dissolve faster?
The rate of dissolving of a solute in a solvent is faster when the solute and solvent are stirred, the solvent is warmer, or the solute consists of smaller particles with more surface area.
Does adding more solute increase solubility?
When the total surface area of the solute particles is increased, the solute dissolves more rapidly. Breaking a solute into smaller pieces increases its surface area and increases its rate of solution.
At what temperature would sugar dissolve most easily?
0 degrees Celsius
How can you increase the dissolution rate of a drug?
Reduction of the particle size often appears to be the first and easiest way to enhance drug dissolution rate. The solubility of drug is often related to the drug particle size. When particle becomes smaller, drug particles have greater interaction with the solvent and then the solubility is increased (4,5).
Which drug can increase the solubility?
Rasool A.A. et al.,[13] improve solubility of many drugs, i.e., diazepam, griseofulvin, testosterone, progesterone, and 17-estradiol in presence of nicotinamide and related compounds. All solubilities were found to increase in nonlinear fashion as a function of nicotinamide concentration.
What increases the rate of dissolution of table salt in water?
Crushing or grinding increases the surface area of the salt that is exposed to the molecules of water. Stirring increases the speed at which the particles of salt come in contact with the water molecules.
How can you improve dissolution?
Several technological methods have been reported for improvement of solubility and dissolution rate of poorly water-soluble drugs, namely (a) reducing particle size to increase surface area; (b) solubilization in surfactant systems; (c) formation of water soluble complexes; (d) use of prodrug and drug derivatization …
How can you reduce the dissolution of time?
decrease with increasing solvent viscosity, and decreasing dissolution rate, dm/ dt. That is, D is inversely proportional to viscosity; D will be discussed shortly. area (A) increases as particle size decreases. So, trituration or micronization of particles will usually speed up dissolution.
What process hinder drug from dissolution?
The formation of agglomerated particles was confirmed by SEM which is described later. On the other hand, the higher the PVP concentration, the higher the viscosity of the diffusion layer around the particles in the medium, which may hinder the drug dissolution.
