A) 1 : 1
B) 2 : 3
C) 1 : 2
D) 2 : 1
Correct Answer: A
Solution :
Aluminium reacts with \[HCl\] and NaOH, as follows: \[2Al+6HCl\xrightarrow{{}}2AlC{{l}_{3}}+3{{H}_{2}}\uparrow \] \[2Al+2NaOH+2{{H}_{2}}O\xrightarrow{{}}2NaAl{{O}_{2}}+3{{H}_{2}}\uparrow \]Hence, ratio of hydrogen evolved in both cases is 1 : 1.You need to login to perform this action.
