Answer 1

. (a)Most plants prefer a pH that falls between 6.1 and 7.0 and if a gardener's soil is too basic or too acidic there are steps that can be taken, such as adding lime (a base) to acidic soil.
(2)Lemon and tamarind juices are acidic in nature. On rubbing with the tarnished surface of Cu vessels, it neutralises the effect of the green coating of basic copper carbonate formed on the surface of copper vessels.

Hence tamarind and lemon juices are used to clean tarnished surface of copper vessels.
