Which of the compounds H₂C₂O₄,Ca(OH)₂,KOH,and HI behave as bases when they are dissolved in water? A)Ca(OH)₂ and KOH B)H₂C₂O₄ and HI C)only HI D)only KOH

Question

Quizplus · Accepted Answer

Ca(OH)2 and KOH are strong bases because they completely dissociate in water to produce hydroxide ions (OH-) which can accept a proton (H+) from the solvent or other sources. 
HS2B12S2B0CS2B12S2B0OS2B14S2B0 and HI are not bases but rather acids. HI is a strong acid and will dissociate into H+ and I- in water, while HS2B12S2B0CS2B12S2B0OS2B14S2B0 is a weak acid that will partly dissociate into H+ and HS2B12S2B0CS2B12S2B0O- ions.
