The correct answer is A.
Electrochemistry: the study of electrical and chemical occurrences or phenomena
Answer : The net ionic equation will be,
![H^{+}(aq)+OH^{-}(aq)\rightarrow H_2O(l)](https://tex.z-dn.net/?f=H%5E%7B%2B%7D%28aq%29%2BOH%5E%7B-%7D%28aq%29%5Crightarrow%20H_2O%28l%29)
Explanation :
In the net ionic equations, we are not include the spectator ions in the equations.
Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.
The given balanced ionic equation will be,
![HCl(aq)+NH_4OH(aq)\rightarrow NH_4Cl(aq)+H_2O(l)](https://tex.z-dn.net/?f=HCl%28aq%29%2BNH_4OH%28aq%29%5Crightarrow%20NH_4Cl%28aq%29%2BH_2O%28l%29)
The ionic equation in separated aqueous solution will be,
![H^+(aq)+Cl^-(aq)+NH_4^+(aq)+OH^-(aq)\rightarrow H_2O(l)+NH_4^+(aq)+Cl^-(aq)](https://tex.z-dn.net/?f=H%5E%2B%28aq%29%2BCl%5E-%28aq%29%2BNH_4%5E%2B%28aq%29%2BOH%5E-%28aq%29%5Crightarrow%20H_2O%28l%29%2BNH_4%5E%2B%28aq%29%2BCl%5E-%28aq%29)
In this equation,
are the spectator ions.
By removing the spectator ions from the balanced ionic equation, we get the net ionic equation.
The net ionic equation will be,
![H^{+}(aq)+OH^{-}(aq)\rightarrow H_2O(l)](https://tex.z-dn.net/?f=H%5E%7B%2B%7D%28aq%29%2BOH%5E%7B-%7D%28aq%29%5Crightarrow%20H_2O%28l%29)
The answer for this is the first option. What you do in here is make a saturated solution and then dissolve more solute in it until there is undissolved solid remaining
The general formula of an acid is HX where H+ acts as the cation while X can be a halogen (Cl-, Fl-, Br-, etc) and acts as the anion. There are also cases where X is an ion like SO42-, which brings two atoms of H in the formula. Strong acids dissociate completely while weak acids do not.
