It means, that, when H 3 PO 4 is dissolved in an aqueous solution then some moles of it remain undissociated in the solution and are not fully ionized to yield H + ions. N a X 2 C O X 3 creates a basic environment, because CO3 binds protons tightly and leaves a lot of OH (-) groups floating about. SALT (wikipedia) In chemistry, a salt is an ionic compound that can be formed by the neutralization reaction of an acid and a base. CsOH would be considered a strong base, and H2CO3 would be a weak acid. Sulphuric acid . H3PO4 15.

Discussion. It doesn't hydrolyse, it dissociates into aquated ions only in water. Important acids . NaOH 12. I'm thinking of their use as Lewis acid catalysts for electrophilic aromatic halogenation. A salt is any compound which can be derived from the neutralization of an acid and a base. Such a reaction is called neutralization reaction because the acid and base properties of H+ and OH- are destroyed or neutralized. The anion is the conjugate base of a weak acid. There are also compounds with more than one acidic proton (polyprotic species). Who are the experts? Nadia L. Rice University. HC2H302 27. FeBr3 6. KCI 2.
