Yes, the pH depends on the temperature.
After studying the color of litmus at different pH.
Neither one is better than the other. Man-made and natural pH indicators do virtually the same exact thing, just with different materials.
The colors of litmus is different; this depends on the pH.
Litmus has different color based reactions depending on whether the contacting substance is acidic or basic. Acids turn litmus red, and bases turn it blue.
Different levels of pH
Acids can turn different colors in indicators like litmus paper. They turn red in litmus paper, yellow in phenolphthalein, and orange in methyl orange.
Litmus paper works by changing color in response to the acidity or alkalinity of a substance. When dipped into a solution, the paper will turn red in acidic conditions and blue in alkaline conditions. This color change is due to the chemical properties of the litmus dye, which reacts differently depending on the pH level of the solution.
No, there is no record of a candy called Litmus lozenge. Litmus is a water-soluble mixture of different dyes extracted from lichens, and it is commonly used to test the acidity or alkalinity of substances.
Online science class does not mean you can just google for answers. Read your textbook!
This is called Litmus paper.
It doesn't have one. The substance that makes litmus paper litmus paper as opposed to just - well, paper - is called "litmus" and it isn't a specific chemical compound but rather a mixture of 10-15 or so different fairly high molecular weight dyes.
Adding washing powder to litmus will not have a noticeable effect on the litmus itself. Litmus is typically used as an indicator to determine acidity or alkalinity by changing color when exposed to different pH levels. Washing powder is a detergent and typically does not interact with litmus in a way that alters its color or properties.
