Question

Define an Arrhenius base and describe properties of bases. Use an example to explain how an Arrhenius base will behave in water.

Answer 1

arrhenius bases are defined as compounds that increase the OH- concentration in an aqueous solution.

as for an example, think about a base like NaOH. this will dissociate into Na+ and OH- in water, thus increasing the OH- concentration.

Answer 2

When you say dissociate you me as in to dissolve

Answer 3

dissolving and dissociating aren't exactly the same thing

dissociating is the process of an ionic compound breaking into ions. dissolving is a more general term that refers to a substance breaking into smaller particles.

ex: sugar dissolves in water, but it doesn't dissociate as it's not ionic and thus cannot split into ions.

Answer 4

dissociating would be the more accurate, preferred term to describe NaOH splitting into ions in water

Answer 5

Okay so its asking how will an arrhenius base will behave in water

Answer 6

This is what I came up with:
For example, when the base (NH3) is dissolved in water, the positive hydrogen ion is removed from the water molecules. Which will leave behind a negative hydroxide ion (OH-) and also a positively charged cation (NH4+)

Answer 7

Or I might just use your example

Answer 8

I think I'm lowkey confusing myself

Answer 9

NH3 isn’t a good choice here because it’s not an Arrhenius base.

Pick a base that has OH like NaOH, KOH, etc.

Answer 10

Okay I will use NaOH
