Last Answer : c. Goes Down.
Last Answer : pH 14 of strong alkali
Description : What pH is expected to a strong alkali to have?
Last Answer : 41974
Description : If any water contains acetic acid then its pH value is less than 7. The pH value of rain water is 5-6. Does this water contain acetic acid ?
Last Answer : Absolutely. There are different types of toxic gases in our atmosphere , such as: SO3, CO2, NO2 , etc. Produces which mixes with rain water and falls to the ground.
Last Answer : The pH value of acid rain is less than 4
Last Answer : The pH value of acid is below 7
Description : A solution which resists change in its pH value on addition of acid/alkali is called the __________ solution. (A) Neutral (B) Ideal (C) Buffer (D) Zero pH
Last Answer : Option C
Description : Buffer solutions have constant acidity and alkalinity because: (1) they have fixed value of pH (2) these give unionised acid or base on reaction with added acid or alkali (3) acids and alkalies in these solutions are shielded from attack by other ions (4) they have large excess of H+ or OH– ions
Last Answer : these give unionised acid or base on reaction with added acid or alkali
Description : What is the value of heat of neutralization when strong acid and base react?
Last Answer : Ans: The heat of neutralization is -57.32 kJ, when strong acid and base react.
