D) Orange and green ph

Answer 1

ANSWER

(b) red and blue. pH stands for potential of hydrogen and is used to measure the quantity of acid or alkaline in substances that are soluble in water, ranging between 1-14, with 7 being the neutral point. Values below 7 exhibit acidic nature and above 7 indicate alkaline. With acids having the least pH, colour of the scale is shown as red. For bases, which are more than 7, the colour on the pH is shown blue.

Answer 2

B) Red and blue

Explanation:

• The pH scale runs from 0 to 14 on the basis of the acidity or basicity of the solution.
• The solution which shows a pH color range from 0 to 7 shows that it is acidic in nature whereas at 7 the solution is neutral and above the 7 the color range shows the basic pH till 14.
• The red color indicate the pH of the solution is acidic. This can be found at the bottom of the pH scale as it shows extreme acidic nature of the solution.
• The blue color of the solution indicates that the solution is basic. This can be seen at the top of the pH scale. This shows extreme basic nature.
