Solution

Solution Steps

Step 1: Identify the Disinfectant for Safety Glasses

The question asks for the disinfectant used to disinfect safety glasses after a laboratory class. The options provided are:

$70\%$ Isopropyl alcohol
$100\%$ Ethanol
$60\%$ Isopropyl alcohol
Accel

Step 2: Determine the Most Common Disinfectant

In laboratory settings, $70\%$ Isopropyl alcohol is commonly used as a disinfectant for safety glasses and other equipment due to its effectiveness in killing bacteria and viruses. It is preferred over $100\%$ Ethanol because the presence of water in $70\%$ Isopropyl alcohol helps in denaturing proteins, which is essential for disinfection.
