Explanation : When all the three solutions namely;
are mixed together a white precipitate of BaS
is formed as a product in the solution along with the soluble by product of Ammonium nitrate which is
Answer:
Explanation:
Since water has a chemical formula of H2O , there will be 2 moles of hydrogen in every mole of water. In one mole of water, there will exist approximately 6.02⋅1023 water molecules.
Explanation:
A polymer forms because the hydrocarbon joins with itself in a polymerization reaction.
Answer:
The true statements are:
The solution is acidic
The pH of the solution is 14.00 - 10.53.
![10^{-10.53}=[OH^-]](https://tex.z-dn.net/?f=10%5E%7B-10.53%7D%3D%5BOH%5E-%5D)
Explanation:
The pH of the solution is defined as negative logarithm of hydrogen ion concentration present in the solution .
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
- The pH value more 7 means that hydrogen ion concentration is less ,alkaline will be the solution.
- The pH value less 7 means that hydrogen ion concentration is more ,acidic will be the solution.
- The pH value equal to 7 indicates that the solution is neutral.
The pOH of the solution is defined as negative logarithm of hydroxide ion concentration present in the solution .
![pOH=-\log[OH^-]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%5BOH%5E-%5D)
The pOH of the solution = 10.53
![10.53=-\log[OH^-]](https://tex.z-dn.net/?f=10.53%3D-%5Clog%5BOH%5E-%5D)
![10^{-10.53}=[OH^-]](https://tex.z-dn.net/?f=10%5E%7B-10.53%7D%3D%5BOH%5E-%5D)
The pH of the solution = ?


Here, the pH of the solution is less than 7 which means that solution acidic.
