HClO2 (aq) + NaOH (aq) ----> H2O (l) + NaClO2 (aq)
ClO2- (aq) + Na+ (aq) ----> NaClO2 (aq)
HCl (aq) + OH- (aq) ----> H2O (l) + Cl- (aq)
H+ (aq) + OH- (aq) ----> H2O (l)
H+ (aq) + NaOH (aq) ----> H2O (l) + Na+ (aq)
H+ (aq) + Na+ (aq) ----> HNa (aq)
ClO2- (aq) + OH- (aq) ----> HClO3 (aq)
HClO2 (aq) + OH- (aq) ----> H2O (l) + ClO2- (aq)
