You can make litmus paper test strips to determine the pH of an aqueous solution by treating filter paper with any of the common pH indicators. One of the first indicators used for this purpose was litmus. Litmus paper is paper that has been treated with a specific indicator - a mixture of 10-15 natural dyes obtained from lichens (mainly Roccella tinctoria) that turns red in response to acidic conditions (pH < 7) and blue under alkaline conditions (pH > 7). When the pH is neutral (pH = 7) then the dye is purple. The first known use of litmus was around 1300 AD by Spanish alchemist Arnaldus de Villa Nova.

How do you test pH of water?
To test the pH of water, you can use a pH test strip or a digital pH meter. Simply dip the test strip into the water and compare the color to the provided chart, or insert the digital pH meter into the water to get a numerical pH reading. Make sure you follow the instructions provided with the testing kit for accurate results.
How do you tell the pH of an acid or alkali?
You can determine the pH of an acid or alkali by using a pH indicator paper or probe. The pH scale ranges from 0 to 14, with lower numbers indicating acids (0-6), 7 being neutral, and higher numbers indicating alkalis (8-14). The color change on the indicator paper or the pH reading on the probe will indicate whether the substance is an acid or alkali.
Is coated paper the same as fine paper or woodfree paper or art paper?
When some type of coating is applied to base paper it is called coated paper. Coated paper is not called as fine paper. Fine paper is bleached writing and printing paper. Woodfree paper is the paper made without using mechanically pulped fiber. Woodfree does not mean free of wood fibers. Art paper is typically the paper used for high class multicolor printing. All coated papers can be categorized as fine paper, woodfree or art paper but reverse is not true as all fine paper or woodfree paper or art paper are not coated paper.
