What do you observe when you dip blue litmus paper into solution with pH lees than 7?
It turns red as acid changes blue litmus to red.
What happens when red litmus is added to soap solution?
The color change to blue, because a soap solution is a basic solution (pH greater than 7).
Why do you test with litmus paper?
The main use of litmus is to test whether a solution is acidic or alkaline. Wet litmus paper can also be used to test water-soluble gases; the gas dissolves in the water and the resulting solution colors the litmus paper. For instance, ammonia gas, which is alkaline, colors the red litmus paper blue. Chemical reactions other than acid-base reaction can also cause a color-change to litmus paper. For instance, chlorine gas turns blue litmus paper white - the litmus paper is bleached.[5] This reaction is irreversible and therefore the litmus is not acting as an indicator in this situation
What color does blue litmus paper turn in the presence of a base?
Blue litmus paper will remain blue in the presence of a base. There wouldn't be any change. Red litmus paper, though, will turn blue. Just remember than the result is red in acids, and blue in bases.
What solution turns red litmus paper into blue?
Any alkaline solutions (pH more than 7). Example: distilled/purified water

Unknown substance turns blue litmus paper pink but does no change pink litmus paper the substance is a?
Acid; Meaning it is ranked less than seven and at least zero on the pH scale.

Any alkaline solutions (pH more than 7). Example: distilled/purified water
Why would litmus paper turn green?
Litmus paper turns green ( rather than pink or red ) because it has been exposed to an alkaline source.
What are the four properties of a base?
bitter taste, slippery feel, and reactions with indicators (turns red litmus paper blue),ph more than 7
What are some differences between acids and basses?
acids: sour, turns blue litmus red, have pH less than 7, produce hydrogen ions bases: bitter, turns red litmus blue, produce hydroxide ions, have pH higher than 7
What is one physical property of an acid?
it has a sour taste in chemical formula always starts with with H+ Ph meter > than 7 litmus paper turns from blue to red.
Is red litmus paper better than blue?
The natural color for litmus paper is blue. When put in an acidic solution the blue paper turns red. Red litmus paper is first mixed with an acid when it is made. This causes the paper to appear red. When put in the presence of a base, the paper returns to its natural blue color.
What colour will Barium Nitrate turn a red litmus paper to?
Barium nitrate has a pH of 5 and is, thus, an acid. So, it will turn a litmus paper red, rather than blue.
