f) What is a universal indicator? What is its advantage?
Answers
1.a solution of calcium hydroxide in water, which is alkaline and turns milky in the presence of carbon dioxide.
2.The advantage of the universal indicator is that it displays a variety of colors over the whole pH scale. This makes it possible to determine an approximate pH of a solution over a range from 1-14. whereas, A commonly used acid-base indicator is litmus.
3.The pH of gastric acid is 1.5 to 3.5 in the human stomach lumen, the acidity being maintained by the proton pump H+/K+ ATPase. The parietal cell releases bicarbonate into the bloodstream in the process, which causes a temporary rise of pH in the blood, known as an alkaline tide.
4.Like strong acids, a strong base dissociates nearly completely in water; however, it releases hydroxide (OH-) ions rather than H+. Strong bases have very high pH values, usually about 12 to 14.
