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 experiment you'll understand more about chemical reactions between acids and bases and the process of titration. ...
In this chemistry experiment, we'll be looking at how acids and bases react. Specifically, we'll be titrating a weak acid with a strong base and observing changes in pH using a pH indicator to find the initial concentration of the acid. Introduction Research Question: How can we use a ...
A very strong acid has a very weak base. Critique this statement. Acids If an acid easily gives off a proton, then it will be classified as a strong acid. However, if an acid partially release a proton is termed as a weak acid. Examples of strong acid include {eq}{\rm{HCl, HN...

Key words: Amphoteric ion exchange fiber, strong-acid/ weak-base, fabrication, structures, adsorption for amino ac- ids INTRODUCTION Among the ion exchangers, ion exchange fibers are the attractive materials for adsorption and separation. Compared with generally used granular ion exchange resins,...

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
are ionised. eg of strong base: NaOH ---> Na+ + OH- eg of weak base: NH3 + H2O ---> NH3+ + OH- when an acid mix/reacts with a base we don't call it's damaged people called neutralisation. Neutralisation is: the H+ of an acid is removed by a base. the...
