Classify each substance as either arrhenius acid or base:
A) HF (aq)
B) Ba(OH)2 (aq)
C) H2SO4 (aq)
D) NH4OH (aq)
My work
A) arrehenius acid
B) arrhenius base
C) arrhenius acid
D) arrhenius base
Am i right
It looks good to me too; however, I should point out that it has been shown that NH4OH does not exist. It is NH3(aq).
In water solution it does this
NH3 + HOH --> NH4^+ + OH^-
It still is an Arrhenius base because it produces OH^- in solution. I don't know the exact date but as early as 1980 there was strong evidence that NH4OH did not exist. Infrared spectroscopy showed only the NH3 gas structure and water structure and no extra bands for "NH4OH" molecule. There is an article in J Chem Ed (1989) explaining WHY it can't exist. Good luck with your chemistry.
Looks good to me.
Yes, you are correct. Here is the classification for each substance:
A) HF (aq): Arrhenius acid - HF can dissociate in water to form H+ ions.
B) Ba(OH)2 (aq): Arrhenius base - Ba(OH)2 can dissociate in water to form OH- ions.
C) H2SO4 (aq): Arrhenius acid - H2SO4 can dissociate in water to form H+ ions.
D) NH4OH (aq): Arrhenius base - NH4OH can dissociate in water to form NH4+ and OH- ions.
Yes, you are correct in classifying the substances as Arrhenius acid or base. I will explain the reasoning behind the classification for each substance:
A) HF(aq) - Hydrofluoric acid dissociates in water to produce H+ ions, making it an Arrhenius acid.
B) Ba(OH)2(aq) - Barium hydroxide dissociates in water to produce OH- ions, making it an Arrhenius base.
C) H2SO4(aq) - Sulfuric acid dissociates in water to produce H+ ions, making it an Arrhenius acid.
D) NH4OH(aq) - Ammonium hydroxide dissociates in water to produce OH- ions, making it an Arrhenius base.
Keep in mind that the classification of substances as Arrhenius acid or base is based on their ability to generate H+ (hydrogen ions) or OH- (hydroxide ions) in water.
