WebMar 23, 2011 · H2Se is a stronger acid than H2S. The bond energy of H2Se is less than H2S, making it easier for the hydrogen atom to leave the molecule. Therefore, H2Se is expected to be a stronger acid than H2S. WebWhich one of these statements about strong acids is true?-All strong acids have H atoms bonded to electronegative oxygen atoms-Strong acids are 100% ionized in water-The conjugate base of a strong acid is itself a strong base-Strong acids are very concentrated acids-Strong acids produce solutions with a higher pH than weak acids
