Answer: The saline distends the uterine cavity (or endometrium) and simplifies the identification of polyps, fibroids, and tumors. The saline outlines the lesion, making it easier to find and evaluate.
Answer: A normal solution contains 1 equivalent mass, in grams, of the solute in 1 litre of solution. Firstly, you calculate the mole mass of ammonium acetate. (77g). Weigh this out in a small, clean beaker.
Add de-ionized water to dissolve the solid, then transfer the solution to a 1 litre volumetric flask, remembering to wash out the beaker three times with small volumes of de-ionized water, and add the washings to the volumetric flask. Similarly rinse the glass rod with small volumes of the water into the flask.
Now add de-ionized water to the 1 litre mark and then mix the solution thoroughly by inverting the stoppered flask many times.
Normality is not used much any more, molarity is more usual, though for this solid the two happen to be the same. Ammonium acetate has the systematic name ammonium ethanoate.
How do you prepare hypertonic saline solution?
For mammals, anything greater than .9% is hypertonic.
Answer: It is basically as solution of salt and water.
There are many concentrations of "saline solution" the most common of which is "normal saline" which is 0.9% sodium chloride (NaCl) in water.
Saline solution is primarily used to irrigate and clean wounds. The irrigation force created by the spray is sufficient to dislodge minor foreign particles such as small twigs and gravel that may have gotten into the wound.
In a hospital and medical setting, saline solution may be administered to aid in hydrating a patient. In Pre Hospital Emergency Care, it is often combined with other drugs (called a bolus). This dilutes the drugs and is administered through an intravenous line. A saline tube will state if it is fit for injection or not. The big tubes generally cannot be injected and will say "Not For Injection" while the smaller tubes are printed with "Injection Solution BP"
Answer: A saline solution enema can be used to cleanse and detox thedigestive system, including the bowels. It is normally made up ofwarm water and salt. Use this with caution since too much salt canmake things worse.
Answer: A saline solution is a homogeneous mixture because its appearanceand composition are uniform throughout the solution. A substance issalt. A saline solution is a combination of the two substanceswater and salt. However, in the salt-water solution, the salt iscompletely dissolved in the water.
Answer: Saline solution is not a pure substance, but it is a homogenousmixture. The components of a saline solution are salt and waterthat are thoroughly blended. An example of a pure substance is justtable salt.
