How to determine the equivalent mass of a metal using hydrogen displacement method ?
Hi ! jeeva, HYDROGEN DISPLACEMENT METHOD :The mass of metal which displaces 11200 ml of hydrogen at NTP from an acid,alkali or alcohol is the equivalent mass of a metal.Equivalent mass (mass given ) Mass of metal/Mass of H2 displace x1.008 = W/m x 1.008 Equivalent mass (volume given) Mass of metal/volume(ml) of H2 displace x 11200=w/v x 11200This method is used for metal which can displace H2 from acid or can combine with H2 (Mg,Zn,Ca etc).Hope you understand,ALL the Best !
