Question

Hi can you paraprase this in your own word.

To demonstrate the measurement of pH. Also, to test the properties of five solution in order to understand the properties of a buffer soltion

Answer 3

The alkaline end of the scale is between pH 7 and 14. At this end of the
scale the hydroxyl or OH–
ions are present in excess. Solutions with these
pH values are created by dissolving a base in an aqueous solution. The
base dissociates to release hydroxyl ions and these make the solution
alkaline. Some of the best known bases are sodium hydroxide, ammonia
and carbonate.
NH3 + H2O ↔ NH4
+ + OH–

The whole scale of pH values in aqueous solutions includes both the
acidic and alkaline ranges. The values can vary from 0 to 14, where
pH values from 0 to 7 are called acidic and pH values from 7 to 14 are
termed alkaline. The pH value of 7 is neutral.
We measure pH for a lot of different reasons, such as:
• to produce products with defined properties – during production it is
important to control the pH to ensure that the end product conforms
with the desired specifications. The pH can dramatically alter the
properties of an end product such as appearance or taste.
• to lower production costs – this is related to the above mention

that is it
