ph 8- p14 is a alkali.
blue for weak alkali (ph 8)
purple for strong alkali (ph14)
Alkali turns litmus paper blue.
Color of litmus will change.Red litmus will change into blue.
Litmus paper is an indicator that changes color in acid and alkali solutions. In an acid solution, litmus paper turns red, while in an alkali solution, it turns blue.
When red litmus is added to an alkali, its colour changes to blue. This is because an alkali is a base and has the property of turning red litmus paper or red litmus solution to blue.
Alkalis turn litmus paper blue. Litmus paper is used as an indicator to determine whether a substance is acidic or alkaline based on the color change it undergoes.
Alkali turns litmus paper blue.
Color of litmus will change.Red litmus will change into blue.
Blue. This answer assumes that you are referring to litmus paper.
Litmus paper is an indicator that changes color in acid and alkali solutions. In an acid solution, litmus paper turns red, while in an alkali solution, it turns blue.
When red litmus is added to an alkali, its colour changes to blue. This is because an alkali is a base and has the property of turning red litmus paper or red litmus solution to blue.
Litmus paper is an indicator used to roughly measure the strength of acids and alkalis on the pH scale. pH1 is a strong acid, pH7 is neutral, pH14 is a strong alkali Alkalis will turn the litmus paper blue, the darker the blue the stronger the alkali
Alkalis turn litmus paper blue. Litmus paper is used as an indicator to determine whether a substance is acidic or alkaline based on the color change it undergoes.
pH.paper tells the strength of an acid and alkali and litmus paper tells that whether the substance is an acid or an alkali.
blue litmus paper turns to red when its in contact with acid
Litmus Paper.
Litmus paper is used to determine if a chemical is acid or alkali. Litmus paper turns red in acidic solutions and blue in alkaline solutions.
if you are working with a strong acid the lithmus paper will turn red.
