    There are only alkali metals in the reaction of high metals.

    Sodium reacts in air 4Na+O2==2Na2O

    Sodium burns in air 2Na + O2 = = Na2O2 (yellow or light yellow) (condition is ignition).

    Sodium reacts with water 2Na + 2H2O = = 2NaOH + H2

    Sodium reacts with a solution of acid living salts.

    Direct acid solution reaction 2Na+2HCl==2NaCl+H2

    To react with the salt solution, first react with the water in the solution 2Na+2H2O==2NaOH+H2

    Then the resulting base and salt react: 2NaOH+CuSO4==Na2SO4+Cu(OH)2

    Sodium changes in air Na Na2O NaOH Na2CO3 Na2CO3?10H2O Na2CO3 (white powder).

    Potassium and water reactions are on the book.

    Potassium reacts with oxygen 2k+o2==ko2

    That's all there is to it.

    Here are some reactions of sodium compounds.

    Sodium peroxide reacts with water 2Na2O2+2H2O==4NaOH+O2

    Sodium oxide reacts with water Na2O+H2O==2NaOH

    Sodium peroxide reacts with carbon dioxide 2Na2O2+2CO2==2Na2CO3+O2

    Sodium oxide reacts with carbon dioxide Na2O=CO2==Na2CO3

    Sodium carbonate and sodium bicarbonate react with hydrochloric acid.

    na2co3+2hci==2naci+h2o+co2↑

    nahco3+hci==naci+h2o+co2↑

    Soluble Na2CO3 NaHCO3

    NaHCO3 dissolves in water with the ionic equation (I remember this is always a test).

    nahco3==na+ +hco3-

    Impurity removal reaction (sodium carbonate mixed with sodium bicarbonate).

    2nahco3=△=na2co3+h2o+co2↑

    Carbon dioxide gas is introduced into a saturated sodium carbonate solution, and there is white cloudiness or crystal precipitation.

    CO2 + Na2CO3 (saturated) + H2O = = 2NaHCO3

    That's all for the time being - the other chapters aren't about metal.

    The reaction chemistry of Na and O2 is (including the reaction of Na and water at room temperature and heating), the reaction of Na2O2 and water and CO2, the reaction of Na2CO3 and NaHCO3 and HCl and NaHCO3 thermal decomposition, and then the reaction of aluminum and acid and alkali, as well as the reaction of AI2O3, Al(OH)3 and alkaline acid, and the reaction of iron and chlorine and ferric ions, which can be separated in the ionic formula according to the strong alkali and strong acid of the ionic reaction. Weak acid, weak alkali precipitation, and the principle that water and gas are not written separately give it a try.
