WebQ. Write balanced equations for the following reactions: (i) Iron (II) chloride solution with sodium hydroxide solution. (ii) Chlorine and cold dilute sodium hydroxide solution. (iii) Zinc and sodium hydroxide solution. (iv) Sulphur dioxide and sodium hydroxide solution. (Give the equation for the formation of the normal salt). WebIn aqueous solution, HCl, NaOH and NaCl remain in dissociated form. So, we can write the given chemical equation as below: H+ + Cl- + Na+ +OH- → Na+ + Cl- + H2O (l) To be considered: (aq) for all ions Net ionic reaction, H+ (aq) + OH- (aq) →H2O (l) It is the ionic reaction for acid-base neutralization reaction. 14 1 Tay Jason

WebAug 15, 2024 · In basic solutions, H 2O 2 oxidizes Mn (II) to Mn (IV), giving a brown precipitate: Mn(OH) 2(s) + H 2O 2(aq) MnO 2(s) + 2H 2O(l) MnO 2 is generally insoluble in acids, but does react with hot concentrated hydrochloric acid to release chlorine gas. In acid solution, H 2O 2 becomes a reducing agent, and the MnO 2 will dissolve: WebNot all proposed single-replacement reactions will occur between two given reactants. This is most easily demonstrated with fluorine, chlorine, bromine, and iodine. ... According to the solubility rules, both NaOH and FeCl 2 are expected to be soluble. If we assume that a double-replacement reaction may occur, we need to consider the possible ... phil town hedge fund performance
