  • Question 1/4
    1 / -0

    The Bronsted acid which gives the weakest conjugate base is

    Solutions

    A strong acid gives a weak base. HCl is the strongest acid among the given options and hence, has the weakest conjugate base.
    NOTE: Among hydrogen halides, the acidic strength increases down the group as the H-X bond length increases. Hence, HCl is a stronger acid than HF.

     

  • Question 2/4
    1 / -0

    Which one of the following is not a Lewis base?

    Solutions

    AICI3 is an electron-deficient compound and hence, it is a Lewis acid because it can accept an electron.

     

  • Question 3/4
    1 / -0

    pKa values of four acids are given below at 25°C. Indicate the strongest acid.

    Solutions

    The lesser the pKa value, stronger is the acid.

     

  • Question 4/4
    1 / -0

    A solution of equal pH and pOH is called a

    Solutions

    Neutral solutions have equal pH and pOH values (7 each) because [H+] = [OH-] = 10-7
