Dorji has a few bottles of soft drink in his restaurant. 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 Dorji decide which drink is to be served to whom?

To serve drinks based on customer preferences for acidity or basicity, Dorji can follow these steps using pH testing methods:

1. pH Testing: Dorji can employ pH test strips or a pH meter to analyze the pH levels of the unlabeled soft drinks. This allows him to identify whether each drink is acidic, basic, or neutral.

2. Customer Preferences:
– Acidic Drink: If a customer requests an acidic drink, Dorji can serve a drink with a pH below 7. Typical acidic drinks like citrus juices or certain carbonated beverages, like cola, tend to have lower pH levels.

– Basic Drink: For customers desiring a basic drink, Dorji can serve a drink with a pH above 7. Drinks such as certain types of mineral water or alkaline water often have higher pH levels.

– Neutral Drink: If a customer prefers a neutral drink, Dorji should serve a drink with a pH close to 7. Pure water or specific sports drinks may have a pH close to neutral.

3. Verification: It’s essential for Dorji to confirm the pH of each drink accurately using reliable pH testing methods to ensure precise matching of the drinks with each customer’s preferences.

By utilizing pH testing to classify the drinks as acidic, basic, or neutral, Dorji can effectively match the beverages with the specific preferences of each customer.
