Why HCl is strong acid in water.

Why salt of strong acid and strong base does not undergo hydrolysis or is neutral to litmus?

Explain the hydrolysis of salt of strong acid and weak base.

Explain why p-nitrophenol is stronger acid than phenol.

The heat of neutralization of a strong acid and a strong base is-60 kj. The heat released by mixing 0.5 moles of HCl and 0.2 moles of NaOH would be

pH of strong acid is………………

Explain with an example, salt of strong acid and strong base does not undergo hydrolysis.

State whether the following statements are true or false: Salts of strong acids and strong bases are basic with the pH value greater than 7.

While performing an experiment, to understand effect of pH on enzyme activity, a student prepared solution of varied pH. He observed that enzyme activity is maximum at a particular range of pH. What is the reason for its maximum activity at a particular range of pH? What would be the effect on enzyme activity if strong acid or strong base is added?
