You can use the paper for cooking, like checking the acidity of coffee or the alkalinity of tea match the color changed strip with the ph scale color chart within ~15 seconds 8 - 11 alkalinity 12 . You use the ph scale to determine the strength of a substance by matching the color of the ph paper with the color on the scale zero being the strongest acid and fourteen being the strongest base this is the homemade indicator, cabbage paper.

Like most ph paper, litmus changes color when exposed to an acidic or basic solution the simple ph scale ranges from 0-14 with 0 being the most acidic, 7 being neutral, and 14 being the most basic or alkaline. Blue litmus test paper is a foolproof ph test to determine if something is acidic the blue litmus test paper does not come with a color chart as it cannot provide you with a defined ph value the test strip will turn red if dipped into an acidic solution (ph 7.

Ph paper, also called litmus paper, is filter paper that is treated with natural water soluble dye from lichens ph paper is used as an indicator to test the acidity of water-based liquids litmus paper is often used to differentiate an acid from a base when ph is less than 45, the paper turns red. Universal indicator, or alkacid, paper is very specific it corresponds to the exact colors on the ph scale with a different color arranged in the order of colors found in the rainbow for every number on the ph scale. Litmus paper is made by soaking paper in a solution of the litmus pigment litmus paper will turn red if it comes in contact with an acid (a substance with ph between 0 and 7) and blue if it comes in contact with a base (a substance with ph between 7 and 14.

A ph indicator is a halochromic chemical compound added in small amounts to a solution so the ph (acidity or basicity) of the solution can be determined visually hence, a ph indicator is a chemical detector for hydronium ions (h 3 o + ) or hydrogen ions (h + ) in the arrhenius model. Universal indicator color charts are used to determine the ph of a solution the charts display the colors and ph values of each ph unit from 4 to 10. Man it is not the color which matters the colour depends on the indicator if u titrate the naoh and hcl u can use phenophthalene or methyl orange the former gives pink while the latter changes from orange to yellow. Ph test paper and indicator sticks are pieces of paper or stiffer sticks that contain ph indicators (chemicals that change color depending on how acidic or basic a solution is) to measure ph, a piece of ph test paper or an indicator stick is dipped into the liquid.
