WebAnswer Molecular weight of Mno 2 = 87 g Molecular weight of Hcl = 4 * 36.5 = 146 g According to chemical reaction 1 g of Mno 2 reacts with 4g of Hcl togive = 146/87 * 1 Or 5 g of Mno 2 reacts with 4g of Hcl to give = 146/87 *5 = 8.4 g of Hcl Hence, 8.4 g of HCl will react completely with 5.0 g of manganese dioxide. Web16 nov. 2024 · MnO 2 particles are almost insoluble in HF, dilute HCl and H 2 O at room temperature, but can present strong oxidability in the acidic solution. Thus, a local oxidation of Si can occur at the contact positions between Si and MnO 2. The existence of HF is to etch the formed SiO 2 off. The main reaction equations in the solution are:
