What is an ionic compound that can be formed as a result of an acid-base reaction? Chemical Equations: The means by which scientists represent chemical reactions are known as chemical equations. Chemical equations are used to give the identity of the substances that must ...
Is cation an acid or base? Again, the cations (K+ and Na+) haveessentially no acidic character, but the anions (CN− and CH3CO−2) are weak bases that can react with water because they are the conjugate bases of the weak acids HCN and acetic acid, respectively. ...
