Web23 okt. 2024 · The H + ions of the HCl gain electrons and are reduced to H atoms, which combine to form H 2 molecules: 2H + (aq) + 2e - → H 2 (g) The overall equation for the reaction becomes: Zn (s) + 2H + (aq) → Zn 2+ (aq) + H 2 (g) Two important principles apply when writing balanced equations for reactions between species in a solution: Web21. The following equation represents an equilibrium reaction. Cr2O7 2–(aq) + H2O(l) 2CrO4 2–(aq) + 2H+(aq) orange yellow Use le Chatelier’s principle to describe and explain the colour change (if any) that might take place when dilute HCl(aq) is added to a solution containing K2CrO4(aq).
