Answer:
This is the balanced equation for that:
FeCl₃ + 3NaOH → Fe(OH)₃ + 3NaCl
Answer:
While they provide very strong evidence for those theories, they aren't proof. In fact, when it comes to science, proving anything

Gaining of electrons
Explanation:
Reduction is the gain of electrons. Oxidation and reduction always occur together, even though they can be written as separate chemical equations.
Answer: a. ![H_2AsO_4^{-}(aq)+H_2O(l)\rightarrow HAsO_4^{2-}(aq)+H_3O^+(aq)](https://tex.z-dn.net/?f=H_2AsO_4%5E%7B-%7D%28aq%29%2BH_2O%28l%29%5Crightarrow%20HAsO_4%5E%7B2-%7D%28aq%29%2BH_3O%5E%2B%28aq%29)
b. ![K_a=\frac{[HAsO_4^{2-}]\times [H_3O^+]}{[H_2AsO_4^{-}]}](https://tex.z-dn.net/?f=K_a%3D%5Cfrac%7B%5BHAsO_4%5E%7B2-%7D%5D%5Ctimes%20%5BH_3O%5E%2B%5D%7D%7B%5BH_2AsO_4%5E%7B-%7D%5D%7D)
Explanation:-
According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.
The balanced chemical equation is:
![H_2AsO_4^{-}(aq)+H_2O(l)\rightarrow HAsO_4^{2-}(aq)+H_3O^+(aq)](https://tex.z-dn.net/?f=H_2AsO_4%5E%7B-%7D%28aq%29%2BH_2O%28l%29%5Crightarrow%20HAsO_4%5E%7B2-%7D%28aq%29%2BH_3O%5E%2B%28aq%29)
Here,
is loosing a proton, thus it is considered as an acid and after losing a proton, it forms
which is a conjugate base.
And,
is gaining a proton, thus it is considered as a base and after gaining a proton, it forms
which is a conjugate acid.
The dissociation constant is given by:
![K_a=\frac{[HAsO_4^{2-}]\times [H_3O^+]}{[H_2AsO_4^-]}](https://tex.z-dn.net/?f=K_a%3D%5Cfrac%7B%5BHAsO_4%5E%7B2-%7D%5D%5Ctimes%20%5BH_3O%5E%2B%5D%7D%7B%5BH_2AsO_4%5E-%5D%7D)
