When it comes to correct usage of Rubbing Alcohol, several individuals behave sceptical. From whether Rubbing Alcohol is safe to consume? Is it ideal for use on the skin? Or Can I Use Rubbing Alcohol on my Dog?
Individuals always come up with a variety of questions. However, along with such queries, the most basic question that revolves around Rubbing Alcohol usage is, Can I mix Rubbing Alcohol with Water?
Today, this article is all about whether Rubbing Alcohol and water goes well together or not? To make the best out of your time, continue reading:
What happens if you mix Rubbing Alcohol with water?
Upon mixing Rubbing Alcohol with Water, both dissolve and form a homogenous solution. Here is a little insight on the same from Science’s perspective:
For forming a Homogenous solution, two or multiple compounds must have molecules that attract to each other.
Molecules are of two types, first polar and second non-polar. Polar molecules are able to form hydrogen bonds. At the same time, non-polar molecules possess an equally distributed balance charge.
While Rubbing Alcohol has both Polar and Non-Polar molecules, water in itself is a Polar molecule.
And when two kinds of Polar molecules come together, they become miscible.
Does mixing Alcohol with water make it weaker?
Yes, if you mix less amount of Rubbing Alcohol and more amount of water, the effectiveness of Isopropyl will reduce.
However, it will still behave worthy for certain tasks, including cleaning, disinfecting, anti-freezing, etc.
How much water do you mix with Rubbing Alcohol?
The amount of water you should mix with Rubbing Alcohol depends upon its concentration and usage. If you have a bottle of 99% Isopropyl, you can dilute it to 30%.
However, if you own a bottle of 50%, diluting it isn’t really a great idea.
How much do you dilute Rubbing Alcohol to clean?
For cleaning and disinfecting surfaces, always mix 50% Rubbing Alcohol and 50% Water.
You can also go for 30:70 water and Rubbing Alcohol, though avoid dropping Alcohol below 50%.
Remember, when we dilute Rubbing Alcohol with more than 50% of water, its effectiveness of killing germs also drops.
According to the Centers for Disease Control and Prevention, 60% to 99% of Rubbing Alcohol are optimal concentrations for killing germs.
Does Denatured alcohol mix with water?
Yes, due to the presence of Hydrogen Bonding in Denature Alcohol and polar solvents in water, both can mix.
For any two compounds to dissolve together, or for any compound to dissolve in water, it must have Polarity or H-Bond.
What is the appearance of the alcohol and water mixture?
As both Rubbing Alcohol and water have transparent, their mixture also has no appearance.
What boils first Rubbing Alcohol or water?
Due to its lower Boiling point, Rubbing Alcohol boils and evaporates faster than water.
- Boiling Point of Rubbing Alcohol: 82 degrees Celsius
- Boiling Point of Water: 100 degrees Celsius
What happens to Rubbing Alcohol when it evaporates?
When Rubbing Alcohol evaporates, it does not disappear but diffuses away as a gas.
Whenever a liquid changes into gas, the fastest molecules break loose from the liquid. It further flies off on its own and blends in with the air around.
Wrapping up…
Yes, you can mix Rubbing Alcohol and water, and this practice is quite common as well. For tasks like cleaning, disinfecting, etc., it requires diluting Rubbing Alcohol first.
There are several commercial antiseptics which are a mixture of Rubbing Alcohol, water, and other ingredients. Even the common hand sanitizers you use daily also contain Rubbing Alcohol and water.
The conclusion says that Rubbing Alcohol as a standalone solvent or supporting ingredient is beneficial either way.
So the next time even if you accidentally drop some water into your Rubbing Alcohol bottle, you can still bring it to use.
