$C a (O H)_{2} + N a_{2} C O_{3} \to C a C O_{3} ↓ + 2 N a O H$
This reaction made the basis of manufacturing of NaOH in earlier days and pH of the solution was found to be greater than 14. This indicates that concentration of NaOH is very high. Hence, pH is greater than 14.
If true enter 1, else enter 0.
