1 An abdominal ultrasound can be used to look for the cause of abdominal pain, evaluate masses in any of the abdominal organs, diagnose kidney stones or liver or gallbladder disease, and evaluate injuries after an accident.2  WebMD offers an overview of abdominal ultrasound.n abdominal ultrasound is used to view organs such as the gallbladder, kidneys and liver. It can be used to investigate abdominal pain or swelling and to diagnose gallstones, kidney stones or cancer.
Dilution drives the pH value of an acidic or basic solution toward 7. The pH values of acidic solutions increase with dilution, while the pH values of basic solutions decrease with dilution. Continue Reading.
The higher the pH, the more basic the solution. On the pH scale, a change of one unit is actually a ten-fold change. For example, pure distilled water is neural at pH 7. A solution at pH 6 is ten times more acidic than pure water, and a solution at pH 5 is 100 times more acidic than pure water.Thus, a pH change of one or two units can seriously affect a great number of organisms in an ecosystem.ll organisms are adapted to survive within particular pH ranges. Most freshwater fish, for example, survive best within a pH range of 5.0-6.0. When acid precipitation falls into a lake, it lowers the pH of the water, thus killing many aquatic organisms.
