Question

5. If pH is less than ............ then water is acidic
a. 6.5
b. 10.5
c. 4.5
d. 12.5​

Answer 1

Answer:

a) 6.5

Explanation:

If pH is less than 6.5 then water is acidic in nature

Answer 2

Answer:

a. 6.5

Explanation:

• pH is an important quantity that measures of how acidic and basic is and reflects the chemical condition of a solution.
• pH scale is used for measuring the acicic and basic nature.It ranges from 0 to 14, the solution which have pH value from 0 to 7 are acidic in nature.The solutiion which have pH value near to the O are strongly acidic.
• pH ranges from 7 to 14 are basic in nature.The solution which shows pH nearly 14 are strongly basic in nature.
• The solution whose pH value are 7, they are neutral in nature,they are neither acidic nor basic in nature.
• Water having pH value less than 7 are considered as acidic in nature.
• The strong acid and base pH value does not depend upon temperature.
• Upon increasing temperature the pH of weak acid increases due to increase in ionization.
