The V/V that we spot on the labels of our bottles, basically means alcohol by volume. Proof also helps to keep with government regulations. If the proof turns out to be more than the government regulated content, it cannot be sold anywhere. The regulated amount in India is 42.8% V/V. Source: mgel.
What does alcohol 70% V V mean?
So, returning to our rubbing alcohol, 70% (v/v) means that for every 100 mL of solution, there are 70 mL of the solute, isopropanol.
What’s the meaning of V V?
Volume concentration of a solution is expressed as % v/v, which stands for volume per volume. This is used when both chemicals in a solution are liquid. For example, when 50ml of sulphuric acid is diluted with 50ml of water, there will be 50ml of sulphuric acid in a total volume of 100ml.
What is 80% vv alcohol?
This is a hand sanitizer manufactured according to the Temporary Policy for Preparation of Certain Alcohol-Based Hand Sanitizer Products During the Public Health Emergency (CoViD-19); Guidance for Industry.
What does 15% V V mean?
There are many ways to express the concentration of a solution. A bottle of wine has the label 13.1% (v/v). That means that 13.1 ml of alcohol are present in every 100 ml of wine. The label on the right states that the wine contains 13.1% (v/v) alcohol (ethanol) where (v/v) is volume per volume.
How do you dilute 95% alcohol to 70%?
For example, to make 70% ethanol from 95% ethanol, take 70 mL of 95% ethanol and add enough water to bring the volume to 95 mL. You will then have 95 mL of 70% ethanol. This works for any dilution and all that is required is a large enough graduated cylinder.
What does alcohol 95% V V mean?
Forms and strengths

Is 80 or 70 alcohol better?
Even though you may think the higher concentration is more effective, experts say 70% is actually better for disinfecting. It has more water, which helps it to dissolve more slowly, penetrate cells, and kill bacteria. The disinfecting power of rubbing alcohol drops at concentrations higher than 80%-85%.
What does alcohol 75% V V mean?
The V/V that we spot on the labels of our bottles, basically means alcohol by volume. … Gunpowder soaked in rum would not burn if the rum contained less than 57.15% ABV. Rum with 57.15% ABV meant it had 100 degrees proof. Hence in India, alcohol content in bottles is 42.8% V/V or 75 Proof.
What is VV in sanitizer?
Ethanol concentrations can be expressed as percentage by volume (v/v) and percentage by weight (w/w).
What does 2% V V mean?
Mass concentration of solution is expressed as % w/v for weight per volume. It can alternatively be abbreviated to m/v for mass per volume. This is used when a solid chemical is dissolved in a liquid.
How do you get VV?
Calculating Percent Volume/Volume (% v/v)
- A percent v/v solution is calculated by the following formula using the milliliter as the base measure of volume (v):
- % v/v = mL of solute/100 mL of solution.
- X % = 5.0 mL HCl/100 mL of solution.
- X/100 = 5.0/100.
- 100X = 500.
- X = 5.0% % v/v.
