The Weak Ionization constant (Ka) for HCOOH is equal to:<br><br><br> Please help me lol
iris [78.8K]

Answer:

Ka=\frac{[H^+][HCOO^-]}{[HCOOH]}

Explanation:

Hello,

In this case, the weak ionization reaction for formic acid is:

HCOOH(aq)\rightleftharpoons H^+(aq)+HCOO^-(aq)

In such a way, we simply recall the law of mass action in order to represent the weak ionization constant, Ka, for such process, by taking into account that the concentration of products is divided over the concentration of reactants as shown below:

Ka=\frac{[H^+][HCOO^-]}{[HCOOH]}

Best regards.

Briefly explain how you will isolate p-tert-butylphenol after you have extracted it into naoh solution.
GREYUIT [131]
To segregate p-tert-butylphenol after you have removed it into NaOH arrangement one would accelerate the p-tert-butylphenol by adding 3M HCl to the cooled arrangement until the point when it is acidic. At that point as the phenol isolates as an oil, one needs to cool the blend in an ice shower to encourage crystallization. The precious stones that are then framed are the p-tert-butylphenol which can be isolated from the arrangement by filtration utilizing the Hirsch pipe
