Make the formula of the highest oxide of a chemical element with serial number 14. Determine its nature. What substance, nitric acid or potassium hydroxide, can this oxide react with? Write the reaction equation.
Let us find in the Periodic Table of Chemical Elements an element with atomic number 14 – this is silicon Si.
The formula of its higher oxide is SiO2.
Since silicon is a non-metal, its oxide has an acidic character. Therefore, it will react with potassium hydroxide.
2KOH + SiO2 → K2SiO3 + H2O
