Write the reaction equation: H2O- H2- HCl- AlCl3- AgCl

1) To obtain hydrogen in its pure form, use the reaction of interaction of water with an active metal:
2H2O + 2Na = 2NaOH + H2
2) To obtain acid HCl, the reaction of interaction of hydrogen with chlorine is used:
H2 + Cl2 = 2HCl
The reaction is carried out under light at room temperature. The resulting HCl product is a gas, so it is passed through an aqueous solution.
3) To obtain the AlCl3 salt, a reaction is carried out between Al and dilute HCl:
2Al + 6HCl (dil.) = 2AlCl3 + 3H2
4) To obtain AgCl, it is necessary to carry out a reaction between AlCl3 and Ag, but since Ag is not an active metal, it will not be able to displace Al from the salt, so the reaction will not proceed.
