A shopkeeper has a few bottles of soft drink in his shop. But, unfortunately, these are not labelled. He has to serve the drinks on the demand of customers. One customer wants acidic drink; another wants basic and third one wants neutral drink. How will he decide which drink is to be served to whom?

Explanation:
The shopkeeper will use a red litmus paper and then he can find out whether a drink is acidic, basic or neutral.
Let him take three bottles of cold drink and take out samples from each of them.....
He will put red litmus paper in one solution, and if paper turns blue it means it is basic drink because base turns red litmus blue..
Now, he will take that blue side of the litmus paper and put it one by one in the two samples.
If the litmus paper remains unaffected then test it with other half of the litmus paper which is red. I still the paper remains unaffected then it means that the drink is a neutral one.
However, if the blue side becomes red then it means that the solution is acidic one. And also to remember that it may happen that the blue side remains unaffected but when tested with the red side he will see that the colour change to blue which means that the solution is basic.....
Pls mark me as the brainliest.....
