Propane gas is a nonpolar molecule, meaning it does not have a positive or negative charge. Bromine water is a polar solvent, meaning it has a positive and negative end. Since propane gas is nonpolar, it does not interact with the polar bromine water, resulting in no colour change.
Yes, other gases such as chlorine or sulfur dioxide can produce a colour change in bromine water. These gases are polar and can interact with the polar solvent, leading to a colour change.
No, the lack of colour change is not dependent on the ratio of propane gas to bromine water. As long as there is a sufficient amount of propane gas present, the reaction will not produce a colour change.
The principles of polarity state that polar molecules will interact with other polar molecules, while nonpolar molecules will not. In this case, propane gas is nonpolar and does not interact with the polar bromine water, resulting in no colour change.
Yes, temperature can also play a role in the reaction between propane gas and bromine water. Lower temperatures can slow down the reaction, resulting in a longer time for the colour change to occur. Additionally, impurities in either the propane gas or bromine water can also affect the reaction and potentially lead to a lack of colour change.
