Answer 1

Answer:

Tea can be described as an agricultural plant, that is industrially important because of the produce of its leaves, when immersed in hot water. Tea, however is an aromatic beverage, that can be prepared in several different ways. Each method of preparation has a certain effect on the acidity of the beverage

Different samples of tea leaves depend upon :-

✒Additives: Additives are elements that are added to tea, after it has been prepared. The addition of additives make tea tastier, healthier, longer lasting, more expensive, etc. and hence alter the pH value

✒Oxidation: The levels of oxidation of the leaves also affect pH value. Highly oxidized tea (e.g. black tea) has different acidity compared to unoxidized or lightly oxidized tea (e.g. Green Tea, Oolong Tea).

✒Addition of Milk: Milk is a colloid that comprises of lactic acid, and hence is responsible for an increase in acidity in tea.

✒Addition of Sugar: Sugar is also responsible for the change in pH value in beverages, as we will find experimentally

✒Type of Water: Boiled tap water in Kathmandu compared to Filtered Water and water that has undergone “Reverse Osmosis” also has different pH levels.
