Question

reaction of potassium sulphite with potassium hydroxide

Answer 1

Potas­si­um is a mem­ber of the first group of the pe­ri­od­ic ta­ble (the el­e­ment is 19ᵗʰ in the pe­ri­od­ic ta­ble). By its phys­i­cal prop­er­ties, metal­lic potas­si­um is a soft met­al of a sil­very white col­or. Like oth­er al­ka­line met­als, potas­si­um is quite re­ac­tive – so it can­not be en­coun­tered in a free state in na­ture. It re­acts read­i­ly with many sub­stances, es­pe­cial­ly with wa­ter (potas­si­um hy­drox­ide forms – “caus­tic potash”). In air, the met­al re­acts very rapid­ly – be­cause of its high re­ac­tiv­i­ty, the met­al is stored un­der a lay­er of kerosene or Vase­line. We can name many dif­fer­ent prop­er­ties and pos­si­ble chem­i­cal re­ac­tions that are char­ac­ter­is­tic for potas­si­um and its com­pounds.
