Help needed Assignment is due Justify that H2SO4 is Arrhenius acid and KOH is Arrhenius base.

irakobra [83]

Answer:

Arrhenius Acid:

According to Arrhenius concept, Acids are proton donors.

Since H₂SO₄ have a proton (H⁺ ion) and it can donate it to be made a sulphate ion, So it is an Arrhenius acid.

See the following reaction =>

H₂SO₄ + H₂O => HSO₄ + H₃O⁺

Arrhenius Base:

An Arrhenius base is a a proton acceptor.

KOH accepts the proton to to made to KOH₂ and a proton acceptor.

See the following reaction =>

KOH + H₂o => KOH₂ + OH⁻

yaroslaw [1]

Answer:

Alternative C would be the correct choice.

Explanation:

The dual compounds were evaluated on something like a TLC plate through three separate additives in conducting a TLC study of ferrocene versus acetylferrocene.
The polar as well as nonpolar ferrocene where nonpolar is about 0.63 with the maximum $R_f$ value, and indeed the polar is somewhere around 0.19 with $R_f$ .
TLC plate (30:1 toluene/ethanol) established with.

The other three choices are not related to the given circumstances. So that option C would be the appropriate choice.
