Book Free DemoAnswer the following questions:
1. How will you show that the hydrogen gas is neutral in behaviour?
Hydrogen exists independently as a (\(H_2\)). It is a neutral molecule; therefore, .
2. Which of the \(Mg\), \(Al\), \(Fe\), \(Sn\), \(Pb\), \(Cu\) and \(Ag\) metal(s) would not evolve hydrogen gas from dilute hydrochloric acid?
It does not matter which acid or metal is used for the reaction; we always get salt and hydrogen gas except for .
do not react with dilute hydrochloric acid, so these metals cannot produce hydrogen gas.
Metals like silver, copper and gold are less reactive than hydrogen. They do not displace hydrogen from dilute acids.
