All chemical equations about Na Al, as well as their compounds

1. Sodium burns in the air (yellow flame) 2Na + O2 Na2O2

2. Sodium reacts with water (floating, melting, swimming, ringing, red) 2Na + 2H2O = 2NaOH + H2

2na + 2h2o = 2na+ +2oh - h2 ↑

3. Reaction of sodium peroxide with water (exothermic reaction, Na2O2 is a strong oxidizing agent and is used for bleaching).

2na2o2 + 2h2o = 4naoh + o2 ↑

2na2o2 + 2h2o = 4na+ +4oh - o2 ↑

5. Soda (soda ash) reacts with hydrochloric acid.

Soda ash solution Na2CO3 + 2HCl = 2NaCl + H2O + CO2 was added dropwise in hydrochloric acid

co32- +2h+ = h2o + co2↑

Add a small amount of hydrochloric acid Na2CO3 + HCl = NaHCO3 + NaCl dropwise to the soda ash solution

co32- +h+ = hco3-

6. Baking soda is heated, and decomposes 2NaHCO3 NA2CO3 + H2O +CO2

There is also 4Na + O2 = 2Na2O (Na is placed in the air).

na2o+co2=na2co3 na2o+h2o=2naoh 2al+2naoh+2h2o=naalo2+3h2↑

2al+3cuso4=al2（so4）3+3cu

Al+Fe2O3=High temperature=Al2O3+2Fe

8al+3fe3o2=high temperature=4al2o3+9fe

2al+6h+=2al3+ +3h2↑

al2o3 + 6hcl = 2alcl3 + 3h2o

Compounds: Na2O, Na2O2, NaOH Na2CO3, Naalo2 Na2S, NaHCO3 Na and halogen NaF, NaCl, Nabr, and sodium thiosulfate Al2O3 FeCl3 FeCl2 Al2(SO4)3 Fe(OH).

NaOH and Al(OH)3: OH Al(OH)3 companion ALO2 Luzhi source 2H2O

NaOH and HCO4: Hoh H2O

Al(OH)3 vs. HCO4: Al(OH)3 3H Al3 3H2O

The most ** oxide corresponding hydrate of Na is NAOH

The most ** oxide corresponding hydrate is Al(OH)3Cl and the most ** oxide corresponding hydrate is HCO4

NaOH and Al(OH)3: OH-+AL(OH)3=ALO2- +2H2O (only this one, there are 2 reactions of Al3+ and OH-).

NaOH and HCO4: H+ +OH-=H2OAL(OH)3HCO4:AL(OH)3+3H+=Al3+ +3H2O

It is sodium hydroxide, aluminum hydroxide, and perchloric acid that react with each other. The ion equation is the neutralization of strong acids and bases, the reaction between strong acids and aluminum hydroxide, and the reaction between strong bases and aluminum hydroxide (there are two kinds).

This also depends on the ratio of Al(OH)3 NaOH.

Because the hydroxide number flushes aluminum only reacts with strong acids and strong bases, and does not react with weak acids and weak jujube bases, an excess of CO2 is introduced into the Naalo 2 solution to generate aluminum hydroxide precipitation, so the reaction equation is ALO 2 - CO 2 +2H 2 O=Al(OH) 3 +HCO3 - So the answer is: ALO 2 - CO 2 +2H 2 O=Al(OH) 3 +HCO3 -

3naalo2+alcl3+6h2o=3nacl+4al(oh)3

This is the most economical way to produce Al(OH)3.

Reason: Naalo2 hydrolysis is alkaline and AlCl3 hydrolysis is acidic, so vertical imitation celery will be "acid-base neutralized".

3naalo2+alcl3+6h2o=3nacl+4al(oh)3

This is the most efficient way to produce Al(OH)3.

The original reason for the disadvantages: Naalo2 hydrolysis is alkaline and AlCl3 hydrolysis is acidic, so it is coincidental to put it together and the key will be "acid-base neutralized".
