Reading the Three Colours
Red or pink on the wetted end means the sample is clearly acidic, as with dilute hydrochloric acid, vinegar or lemon juice. Purple places the sample in the middle band, which includes pure water and neutral salt solutions such as common salt in water. If the strip stays blue, the sample is alkaline; red litmus paper, which turns blue in bases, confirms it. Close the vial after taking a strip, so acid fumes in the lab cannot redden the rest.
