The concept of conjugate acid-base pair is related to Bronsted-Lowry acid-base theory and according to this theory, acid is a proton (H^+) donor while base is a proton acceptor . The conjugate base of a weak acid is a weak base. (of two complex numbers) differing only in the sign of the imaginary part as 4 + 3i and 4 -- 3i c. Your Account Isn't Verified!
