How to check the state of a compound at certain temperature?
Answers
The easiest way to determine whether a compound can conduct a current is to identify its molecular structure or composition. Compounds with strong conductivity dissociate completely into charged atoms or molecules, or ions, when dissolved in water. These ions can move and carry a current effectively. The higher the concentration of ions, the greater the conductivity. Table salt, or sodium chloride, is an example of a compound with strong conductivity. It dissociates into positively charged sodium and negatively charged chlorine ions in water. Ammonium sulfate, calcium chloride, hydrochloric acid, sodium hydroxide, sodium phosphate and zinc nitrate are other examples of compounds with strong conductivity, also known as strong electrolytes. Strong electrolytes tend to be inorganic compounds, meaning that they lack carbon atoms. Organic compounds, or carbon-containing compounds, are often weak electrolytes or are nonconductive
