which of these are strong electrolytes, weak electrolytes and non electrolytes.
H2SO4
FeCl2
HClO
AgCl
I put AgCl as a non
H2So4 and HCl as strong
FeCl2 as weak but the computer told me my answer is wrong Can some one help please?
H2SO4 is a tricky question and one that I would not know how to answer if I had to input to a computer. The first H is a strong electrolyte, the second one is weak (k1 ionizes 100%; k2 = about 10^-2).
FeCl2 ionizes 100%
HClO is a weak electrolyte
AgCl is a strong electrolyte BUT it isn't very soluble.
To determine whether a substance is a strong electrolyte, weak electrolyte, or non-electrolyte, we need to examine its ability to conduct electricity when dissolved in water.
Strong electrolytes completely dissociate into ions when dissolved in water, resulting in a high concentration of ions and hence a strong electrical conductivity. Weak electrolytes partially dissociate into ions, resulting in a lower concentration of ions and a weaker electrical conductivity. Non-electrolytes do not dissociate into ions and do not conduct electricity in water.
Let's analyze each of the compounds:
1. H2SO4 (sulfuric acid):
Sulfuric acid, H2SO4, is a strong electrolyte. It dissociates completely into H⁺ and SO₄²⁻ ions when dissolved in water, resulting in a high conductivity.
2. FeCl2 (iron(II) chloride):
Iron(II) chloride, FeCl2, is also a strong electrolyte. It fully dissociates into Fe²⁺ and 2Cl⁻ ions when dissolved in water.
3. HClO (hypochlorous acid):
Hypochlorous acid, HClO, is a weak electrolyte. It partially dissociates into H⁺ and ClO⁻ ions when dissolved in water, resulting in a lower concentration of ions and a weaker conductivity.
4. AgCl (silver chloride):
Silver chloride, AgCl, is a non-electrolyte. It does not dissociate into ions when dissolved in water and does not conduct electricity.
Based on this analysis, your answer is incorrect. The correct classification is:
- Strong electrolytes: H2SO4 and FeCl2
- Weak electrolyte: HClO
- Non-electrolyte: AgCl
