What does it mean to say that a solution is a homogeneous mixture? What is the definition of a saturated solution? Explain what a saturated solution is. Colloidal particles eventually separate from the solvent. Suggest an explanation. Give an example of a substance that refracts light. How and...
\\ 2. If red litmus paper is used to test the substance it would turn what color? \\ a. basic; red b. acidic; red c. acidic; blue d. basic; blue An acid turns the indicator litmus to what color? What is the color of phenolphthalein in an acidic solution? Do acid...
Litmus papers are often confused with universal pH indicator strips, but the latter is actually a different — and arguably better — technology. Litmus paper has limits to its usefulness. While red litmus paper is effective atdetermining whether a substance is acidic, and vice-versa for blue li...
Phenolphthalein is a mild acid used in both medicine as an ingredient in laxatives and in science as a substance for testing the...
total number ofhydrogen ionsthat occurs in a substance in the form of fixed and volatile acids. Therefore, this type of acidity typically includes potential hydrogen ions that can get released and hydrogen ions that are already in the solution. This is also known as the total acid number or ...
For what purpose is it used? (b). How does a universal indicator work? (c). Water is a neutral substance. What colour will you get when you add a few drops of universal indicator to a test-tube containing water? View Solution Five solutions A,B,C,D and E when tested with ...
CO2 will readily dissolve in distilled water (or any water, but more so in distilled because it's 'empty' water). This can be proven. Add phenolphthalein indicator to distilled water. Let's presume the pH was 7 or just slightly below. the indicator should be a slight pink color. If yo...
For example, Take a sample of an unknown solid substance. The chemists first use “qualitative” methods to identify what type of compound is present in the sample; then he adopts the quantitative analysis procedure to determine the exact amount or the quantity of the compound present in the ...

Fiber is part of plants or carbohydrates that the body can’t break down easily during the digestion process. Adding this substance to a person’s diet generally relieves constipation. Experts divide it into two large classes, soluble and insoluble. Soluble fiber absorbs water easily to form a...
