<u>Answer: </u>The concentration of 
in the solution is 
<u>Explanation:</u>
pH is defined as the negative logarithm of hydrogen ion concentration present in the solution.
![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
.....(1)
We are given:
pH of solution = 2.5
Putting values in equation 1, we get:
![2.5=-\log [H^+]](https://tex.z-dn.net/?f=2.5%3D-%5Clog%20%5BH%5E%2B%5D)
![[H^+]=10^{-2.5}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-2.5%7D)
![[H^+]=3.16\times 10^{-3}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D3.16%5Ctimes%2010%5E%7B-3%7DM)
Hence, the concentration of in the solution is
A)
Each mole of Rb₃PO₄ will release:
3 moles of Rb⁺
1 mole of PO₄⁻³
So a total of 4 moles of ions are released per mole.
If there are 0.5 moles, 2 moles of ions will be released.
B)
Each mole of Cr₂(SO₄)₃ will release:
2 moles of Cr⁺³
3 moles of SO₄⁻²
So a total of 5 moles of ions are released per mole.
When there are 0.5 moles, 2.5 moles of ions will be released.
A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
A characteristic of strong base is that
<span>It removes H+ ions from solution.
</span>
A strong base can dissociate into ions that can react with an acid resulting to the removal of H+ ions from a solution. A weak base only dissociates partially which removes less H+ ions in a solution.

B)</h3>
Explanation:
A genus is a group that includes a number of very closely related species; a species within a genus includes populations of organisms that can potentially interbreed.
