Question

Write equation for ionisation of weak base KF

Answer 1

When do you do the h2o over the arrow?

Answer 2

In the compound KF, the weak base is actually the fluoride ion \(F^-\)

The equation goes:

\(F^-+H_2O \rightarrow HF+OH^-\)

Answer 3

Thanks, when is it +h20, and when is it an arrow with an h2o on top?

Answer 4

For instance, when water is the agent that triggers or helps the reaction without being a reactant.

For instance, when potassium fluoride undergoes dissociation:

\( \large KF_{(s)} \longrightarrow K^+_{(aq)} + F^-_{(aq)} \)

you can write \(H_2O\) above the arrow (I do not know the LaTeX command enabling this).

Answer 5

got it. thankyou so much :)
