Test the ph of the solution: tear off a strip of test paper, add the solution with a rubber dropper, change color in half a second and compare with the colorimetric card on the package;Or take a small amount of solution, directly wet the liquid with the test paper, half a second after the package on the color card contrast;You can also take a small piece of test paper on a surface dish or glass piece, dip the tested liquid into the middle of the test paper with a clean and dry glass rod, observe the stable color, compare with the standard color card, and judge the properties of the solution.
Check the acidity or alkalinity of the gas: first wet the test paper with distilled water, stick it to one end of the glass bar, and then send it to the container with the gas to be measured near the mouth, observe the change of color, judge the nature of the gas.(The test paper should not touch the wall of the device)
