Paper that is blue will turn/stay _____ in the presence of a strong base.
Paper that is blue will turn/stay _____ in the presence of a strong base
A pH-paper (as Merck art. 9565) is red in a basic solution.
For litmus the color is blue at high pH.
just saying that I'm 12 and i know the answer!an acid will turn red in litmus paper or a pinkcolour.if it is a week acid it will turn yellow or green. :)
strong base
When a strong acid and a strong base mix, all acidic protons will react with every basic molecule until one or the other runs out. The curve for a titration of a strong acid with a strong base will change slowly at first, and dramatically when the equivalence point (where the number of moles of acid is equal to the number of moles of base) is reached. The reaction, like all acid-base reactions, is fast.
it is base
well as we know if we want to test a substance to see if its a base then we use red litmus paper and for an acid we use blue litmus paper. So if we are using blue litmus paper that means we are obviously testing to see if we have an acid right? So if we see it turn pink then that means that are substance is an acid but it is not very strong and also has some of a base to it. If you want to see what i mean look up a PH scale. Hope this helped. :)
Litmus paper that is blue will turn or stay in ______ the presence of a strong base?
orange
Stay blue
It will Remain Same. Cause Base Turns Red Litmus Paper into Blue. So blue litmus paper will remain same.
The red litmus paper turns green because the acid (represented by red) and the base ( represented most commonly by blue) mix their Ph and become a nuetral. In short, red litmus paper in a base turns green.
Litmus paper is used to indicate whether a substance is acidic or basic. Blue litmus paper turns red in the presence of an acid, while red litmus paper turns blue in the presence of a base.
Phenolphtalein is an indicator used to find the endpoint of a reaction (specifically an acid-base reaction). It has a pH range of 8.3 to 10.0 which means it can be used for a strong acid to strong base titration or a weak base to strong acid titration. Phenolphthalein is clear when it is in the presence of acid and pink when it is in the presence of a base.
green
The trick is to make a strong 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.
When litmus paper touches an acid, the paper changes to red. When it touches a base, the paper changes to blue. By comparing the color the litmus paper changed to by a chart, you could determine how strong or weak that acid or base is.
