Answer:
A substance that has a specific shape and volume changes to a substance that has a specific volume,
A substance that has a specific volume changes to a substance that has a specific shape and volume.
Explanation:
Answer:
pCl⁻ = 0.54
Explanation:
First we <u>calculate how many Cl⁻ moles are coming from each substance</u>, using the <em>given volumes and concentrations</em>:
- 0.12 M NaCl * 0.10 L = 0.012 mol NaCl = 0.012 mol Cl⁻
- 0.18 M MgCl₂ * 0.23 L = 0.0414 mol MgCl₂ = (0.0414 * 2) 0.0828 mol Cl⁻
The final volume of the mixture is = 0.10 L + 0.23 L = 0.33 L
Now we <u>calculate [Cl⁻]</u>, using the<em> total number of Cl⁻ moles and the final volume:</em>
- [Cl⁻] = (0.012 mol + 0.0828 mol) / 0.33 L = 0.29 M
Finally we <u>calculate the pCl⁻ of the resulting solution</u>:
The major ionic species present in aqueous solution of sodium sulfate is
2 Na+ and SO4^2-
<u><em>explanation</em></u>
When electrolyte dissolve in water they dissociate into ions.
There are two type of electrolyte that is strong and weak electrolyte.
Sodium sulfate is a strong electrolyte and therefore it dissociate completely into ions as below
Na2So4 → 2 Na+ (aq) + So4^2- (aq)
