Resorcinol is so named because of its derivation from ammoniated resin gum, and for its relation to the chemical orcin. Solid NaOH has a melting point and boiling point of approximately 604°F and 2534°F. The melting point was determined to be 43.7-44.3 o C. That is less then the literature melting point and that could be due to it being not as pure because mentioned earlier there could've been overheating which caused the reaction to have some damage.

77, No. Stable under normal conditions. Periodic trends in boiling point closely follow periodic trends in heat of vaporization. Sodium ion is the principal cation of the extracellular fluid and plays a large part in the therapy of fluid and electrolyte disturbances. Incompatible materials metals. 10.5.
