aqueous solution one in which water is used as the solvent.
an aqueous suspension of bacille Calmette-Guérin
for instillation into the bladder to activate the immune system
in treatment of superficial bladder cancers. It reduces the risk of a subsequent bladder cancer developing, although the exact mechanism of action is unknown.
buffer solution one that resists appreciable change in its hydrogen ion concentration (pH) when acid or alkali is added to it.
) imprecise term for colloid
hyperbaric solution one having a greater specific gravity than a standard of reference.
hypertonic solution one having an osmotic pressure greater than that of a standard of reference.
hypobaric solution one having a specific gravity less than that of a standard of reference.
hypotonic solution one having an osmotic pressure less than that of a standard of reference.
isobaric solution a solution having the same specific gravity as a standard of reference.
isotonic solution one having an osmotic pressure the same as that of a standard of reference.
molar solution a solution in which each liter contains 1 mole of the dissolved substance; designated 1 M. The concentration of other solutions may be expressed in relation to that of molar solutions as tenth-molar (0.1 M), etc.
a solution in which each liter contains 1 equivalent weight
of the dissolved substance; designated 1 N.
ophthalmic solution a sterile solution, free from foreign particles, for instillation into the eye.
saturated solution one in which the solvent has taken up all of the dissolved substance that it can hold in solution.
one containing an irritant substance (sclerosing agent
) that will cause obliteration of a space, as in sclerotherapy
standard solution one that contains in each liter a definitely stated amount of reagent; usually expressed in terms of normality (equivalent weights of solute per liter of solution) or molarity (moles of solute per liter of solution).
supersaturated solution an unstable solution containing more of the solute than it can permanently hold.
volumetric solution one that contains a specific quantity of solvent per stated unit of volume.
so·lu·tion(soln, sol) (sŏ-lū'shŭn)
1. The incorporation of a solid, liquid, or gas into a liquid or noncrystalline solid resulting in a homogeneous single phase.
2. Generally, an aqueous solution of a nonvolatile substance.
3. The termination of a disease by crisis.

Patient discussion about solution
Q. WHAT ARE THE CAUSES N SOLUTION TO PNEMONIA? I HAVE A FRIEND WITH THIS DISEASES WHAT SUGGESTION CAN I GET FROM U AND TELL TO MY FRIEND I WILL BE WAITNG FOR YOUR SUGGESTION.
A. Pneumonia is an infectious disease of the lungs, and is caused by various bacteria, viruses or fungal infections. The most common pneumonia is caused by viruses, and the treatment is usually symptomatic
(anti caugh and fever, etc.), however, because there are many bacterias that can cause it as well, you should recommend to your friend to go see a doctor and get some antibiotic medications.
Q. Can you suggest an immediate solution for this, please? My niece is 22 years old. She was very excited about being a single mother. She was staying with her boyfriend when she announced that she was pregnant. About 5 weeks of pregnancy she had a fight with her boyfriend that ended up in him shoving her. She fell violently to the ground. She is complaining of spotting and cramps. I am worried if anything has gone wrong. Can you suggest an immediate solution for this, please?
A. I want to add, that the physical act of violence done to her and the unborn child might have been criminal assault. If she or the unborn child were harmed, she could file charges. There is no excuse for the boyfriend's irresponsible behavior. If she is in any danger from this guy doing this again, she could seek help at a shelter for battered women, or even better staying with someone in her family.
