As the pH of a substance rises from 7, it turns from a weak base to a strong base. A strong acid such as HCl, when mixed with water, will separate into molecules of hydrogen ions and chloride ions. That is called dissociation. Strong acids dissociate more completely than weak acids, ...
In this chemistry experiment, you'll be learning how to find the concentration of an acid using titration with a weak base. By the end of this...
Is CH3NH2 classified as a strong acid, weak acid, strong base, or weak base? Explain. Is (CH3)2NH classified as a strong acid, weak acid, strong base, or weak base? Explain. Is HNO2 classified as a strong acid, weak acid, strong base, or weak base? Explain. Is CH3COOH...
These can be strong and weak. Answer and Explanation: Answer and Explanation: Part A. The equation of ionization is: {eq}H_2SO_4\to 2H^++SO_4^{2-} {/eq} It is a strong acid. Part B. The equation of...Become a member and unlock all ...

strong acid cation exchangersweak baseThe gel diffusion kinetics of ion exchange on strong acid cation exchangers with the participation of a weak base is considered. The kinetics of benzocaine desorption from sulfonated polycalixarene and CU-23 30/100 sulfocationite has been experimentally studied. ...
This weak acid-strong base type charge-mosaic membrane exhibited quite high ion selectivity in comparison with previous strong acid-strong base type charge-mosaic membranes. 展开 DOI: 10.1016/S0376-7388(00)85098-X 被引量: 30 年份: 1989
