Nitric acid and calcium hydroxide react to form calcium nitrate and water.
The molecular equation is as follows:
2HNO3 (aq) + Ca(OH)2 (aq) = Ca(NO3)2 (aq) + 2H2O (l)
So the formula of calcium nitrate, the salt formed in this reaction is Ca(NO3)2 .
Water here seem to be the only real product. It is formed from the OH+ of the hydroxide and the H+ of the acid which combine to form two water molecules.
Calcium and Nitrate ions remain unchanged before and after the reaction and are thus known as spectator ions.
Answer:C:Carbon
H:Hydrogen
O:Oxygen
Explanation:Every element is represented by a letter that is easy to tell which element it is so you don't have to get confused.
Answer : The concentration of 
ion is, 
Solution : Given,
pH = 4.20
First we have to calculate the pOH.
As we know that,
Now we have to calculate the concentration of ion.
![pOH=-\log [OH^-]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%20%5BOH%5E-%5D)
![9.8=-\log [OH^-]](https://tex.z-dn.net/?f=9.8%3D-%5Clog%20%5BOH%5E-%5D)
![[OH^-]=1.58\times 10^{-10}M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D1.58%5Ctimes%2010%5E%7B-10%7DM)
Therefore, the concentration of ion is,
The answer will be b. membrane.
