What is 70 percent Rubbing Alcohol?
70 percent rubbing alcohol, also known as isopropyl alcohol, is a solution containing 70% isopropyl alcohol and 30% water. This concentration is effective for disinfecting surfaces and is commonly used in medical settings and households for sanitizing. The presence of water in the solution helps slow the evaporation of alcohol, allowing for a longer contact time on surfaces for effective germ killing. It's important to use it safely, avoiding ingestion and contact with sensitive areas.

In what proportion should 95 percent percent alcohol be mised with 30 percent percent alcohol to make 70 percent percent?
x = volume of 95% y = volume of 30% so (x+y) is volume of 70% 0.95 x + 0.30 y = 0.70(x+y) 0.95 x + 0.30 y = 0.70x + 0.70y 0.25x = 0.40y x/y = 0.40/0.25 = 8/5 for every 8 volumes of 95% mix in 5 volumes of 30%the volumes can be ml, liters, cups, pints etc.
