Silica dissolves in NaOH solution to form:

Silica dissolves in NaOH solution to form:

  • A. quartz
  • B. sodium silicate
  • C. carborundum
  • D. jaspar

Step-by-step solution

Silica (SiO2) reacts with sodium hydroxide (NaOH) to produce sodium silicate (Na2SiO3) and water. This is a classic acid-base reaction where silica acts as an acidic oxide. Quartz, carborundum, and jaspar are other forms or compounds of silicon, but not the product of this reaction.
