Metal sodium (potassium, lithium) and the reactions involved

Potassium, sodium, and lithium are a kind of alkali metals with high chemical reaction activity.

1.

Potassium, sodium, and lithium are all active and need to be stored in isolation from air and water.

Sodium (bell) cannot be used to dry the halogenated reagent, because in the presence of sodium (potassium), the halogenated reagent will undergo a self-coupling reaction accompanied by a violent exotherm

Fires caused by metal lithium, sodium, and potassium cannot be extinguished with water or foam fire extinguishers, but sodium carbonate dry powder fire extinguishers should be used

2.

(1) Keep away from the water source when taking and cutting sodium (potassium), and keep the area around the work surface dry

(2) Do not cut very small and thin.

(3) The paper for wiping metallic sodium (potassium) can be quenched with absolute ethanol and cannot be thrown directly into the trash can

(4) For reactions above 500 mL, it is best to use mechanical stirring.
