Question

which of the following metal can displace hydrogen from HCL solution? write apperciate equations for any reaction that can occur Al, Cu,Ag​

Answer 1

Answer:

Al+HCl=AlCl3+H2(cu andAg can't react because they are less reactive

Answer 2

Answer:

Al

Step-by-step explanation:

Al is more reactive than H so it can displace H fro HCl by following reaction

2Al+ 6HCl -----> 2AlCl3 +3H2↑

Cu and AG on the other hand are less reactive than H so reaction between them will not occur
