Into b concentrated nitric acid is to be poured , and into d a saturated solution of
sulphate of zinc , which will here have a stronger effect than sulphuric acid
diluted with one - tenth of water . The combination of the different pairs is made
like that ...

M. Becquerel varied these experiments in many ways , and with the aid of this
apparatus arrived at the following conclusions : “ The maximum of intensity is
obtained by immersing the copper plate in a solution of nitrate of copper , and the

In process of time , indeed , when a considerable proportion of sulphate of zinc
has been dissolved in the fluid , the quantity of disengaged hydrogen is found to
diminish , and a thin film , composed partly of metallic zinc , and partly of
