Question

a person X tested the pH of his salaiva immediately after drinking coffee predict pH range of salaiva and colour of the pH strips​

Answer 1

Answer:

The pH range of saliva of person immediately after drinking coffee is 4.85 to 5.10

colour of pH strips is light green

hope it helps :)

Answer 2

Answer:

The pH range will be from 4.85 to 5.10.  The colour of the pH strips will be yellow or light green.

Explanation:

• Coffee is a slightly acidic substance
• The pH scale determines how acidic or basic water is. The range is 0 to 14, with 7 representing neutrality.
• Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7.
• In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.
• In chemistry, the pH scale is used to define the acidity or basicity of an aqueous solution.
• Historically, pH stood for the "potential of hydrogen."
• The pH values of acidic solutions are typically lower than those of basic or alkaline solutions.
• Coffee has an acidic pH range of 4.85 to 5.10 as a result of the coffee beans' release of acids during the brewing process.

Since coffee is acidic, after consuming coffee, the person's saliva will also be acidic.
