Navneet has a few bottles of soft drinks in his restaurant. But, unfortunately, these
are not labelled.Now 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 Dorji decide which drink is to be served to whom?

he should use a universal indicator which shows change of colour in all 3 conditions
Step-by-step explanation:
he should take a small sample of each drink test it with the universal indicator
the drink that shows the shades of red is acidic
and
the drink that shows the shades of blue is basic in nature
and
the drink that shows the colour green is neutral in nature
thus he will be able to serve requested drinks to their respective costumers
