An acidic solution will turn blue litmus paper red
A basic solution will turn red litmus paper blue
A neutral solution does not have effect on blue or red litmus paper.
Therefore, in order to establish whether solution that resulted from adding sodium hydroxide to copper(II) nitrate in step two of Experiment 4 is basic, we could carry out a litmus paper test.
If the solution turns red litmus paper blue, then it is basic.
Hence, we could establish whether the solution in step two of experiment 4 is basic by carrying out litmus paper test. If the solution turns red litmus paper blue, then it is basic.
