Write the reaction equations: SiO2 – Si – SiO2 – Na2SiO3 – H2SiO3 – SiO2
| August 7, 2021 | education
SiO2 + Mg = Si + 2MgO – the reaction proceeds on heating.
Si + O2 = SiO2
SiO2 + Na2O = Na2SiO3 – the reaction proceeds when the reagents are melted.
Na2SiO3 + 2HCl = 2NaCl + H2SiO3 – as a result of the reaction, a precipitate is formed, which is a mixture of various silicic acids.
H2SiO3 = H2O + SiO2 – the reaction proceeds when heated.
