We can solve this problem using the long hand solution, wherein we 1 by 1 analyze the different equilibrium reactions or by simply using the Henderson Hasselbach equation. The equation is
pH = -log(pKa) + log (salt/acid)
since the acid and the salt have the same concentration, the log (salt/acid) term is equal to zero.
thus
pH = -log(1.73*10-5)
pH = 4.76
please be careful with the negative sign
Answer:
It is not true that this is an example of a chemical reaction. This is a typical example of physical reaction.
Most physical changes are often phase changes.
A phase change is a change in the physical state of a body.
In this change, it is from solid to liquid.
Now new substances are formed.
When substances are changed from one form to another, it is a physical change.
In a chemical change, a new substance is formed at the end of the process.

Answer:
Does a reaction occur when aqueous solutions of copper(II) nitrate and calcium chloride are combined?
Explanation:
The given reaction is an example of a chemical double displacement reaction.
The mutual interchange of the ions takes place.
The balanced chemical equation of the reaction is:
All the products formed are also highly soluble.
So, all the ions are spectator ions.
Hence, all will cancel with each other and ions remain in the net ionic equation and hence, the reaction does not take place.
A ecosystem is SUSTAINABLE if it can continue to function over long periods of time.
