Which of the following compounds is an Arrhenius base in water?
snow_lady [41]
Arrhenius model considers a base a compound that produces OH(-)

H2SO4 produces H(+) and is an acid

C6H12O6 is an organic product, sugar, that does not produce OH(-)

HOClO2 = HClO3, which produces H(+) and is an acid

NH3 is believed to ionize in water and produce NH4(+) and OH(-).

As per this the answer is NH3.

Nevertheless, NH3 is not a good example of bases as per Arrhenius model, because it is not so evident that NH3 produces OH(-).
