How to identify Strong, weak and non-electrolytes?
Strong weak and non electrolytes First we have to study about electrolytes Electrolytes are chemicals that break down into ions in the water. Aqueous solutions containing electrolytes conduct electricity.
Strong electrolytes
The strong electrolytes include acids strong , strong bases and salts. These chemicals dissociate completely in ions in an aqueous solution.
Molecular examples
- HCl – hydrochloric acid
- HBr – hydrobromic acid
- HI – hydroiodic acid
- NaOH – hydroxyde de sodium
- Sr (OH) 2 – strontium hydroxide
- NaCl – sodium chloride
Weak electrolytes
The weak electrolytes break only partially in the ions in the water. The weak electrolytes include weak acids, weak bases and a variety of other compounds. Most nitrogen-containing compounds are weak electrolytes.
Molecular examples
- HF – hydrofluoric acid
- CH 3 CO 2 H – acetic acid
- NH 3 – ammoniac
- H 2 O – water (dissociates weakly in itself)
Non-électrolytes
Non-electrolytes do not break into ions in the water. Common examples include most carbon compounds , such as sugars, fats and alcohols.
Molecular examples
- CH 3 OH – methyl alcohol
- C 2 H 5 OH – ethyl alcohol
- C 6 H 12 O 6 – glucose
