Question

Sodium chloride, NaCl iron(III) nitrate, Fe(NO3)3 calcium nitrate, potassium hydroxide, KOH ammonium fluoride, NH4F In your answer write a balanced chemical reaction equation for any relevant precipitation reaction, including the states of all chemic?

Answer 1

Well, you have proposed neither a specific question nor a specific reaction....

Explanation:

All of the salts you detail, speciate in aqueous solution to give aquated ions....i.e.

`Fe(NO_3)(s) stackrel(H_2O)rightleftharpoonsFe^(3+) + 3NO_3^(-)`

Nitrates are soluble, but addition of hydroxide salts will precipitate the iron salt as ferric hydroxide...

`Fe(NO_3)_3(aq) + 3HO^(-) rarr Fe(OH)_3(s)darr`

Note also that fluoride salts are WEAKLY basic....

`F^(-) + H_2O(l) rightleftharpoons HF(aq) + HO^(-)`

And for ammonium fluoride you got a real dog's breakfast of a salt...the salt of a weak acid, `NH_4^+`, and a moderately strong base, `F^(-)`.
