Question

comparison between different sample of water on the basis of colours sMel acidity and conductivity​

Answer 1

Explanation:

These strips of paper can measure the difference 0.2-0.3 pH in a sample. Litmus paper changes color based on whether the sample solution is acidic or basic, turning red or blue, respectively. ... The higher the dissolved salt/ion concentration, the more conductive the sample and hence the higher the conductivity reading.
