Ion exchange Ion exchange
ion exchange The exchange of ions of the same charge between a solution (usually aqueous) and a solid in contact with it. The process occurs widely in nature, especially in the absorption and retention of water-soluble fertilizers by soil. For example, if a potassium salt is dissolved in water and... Read more

acid-base indicators acid-base indicators
acid-base indicators organic compounds that, in aqueous solution, exhibit color changes indicative of the acidity or basicity of the solution. Common indicators include p -nitrophenol, which is colorless from p H 1 to 5 and yellow from p H 5 to 9; methyl orange, yellow in basic and neutral... Read more
nonmetal nonmetal
nonmetal chemical element possessing certain properties by which it is distinguished from a metal . In general, this distinction is drawn on the basis that a nonmetal tends to accept electrons and form negative ions and that its oxide is acidic. Nonmetals are poor conductors of heat and...
