Define and explain the difference between quantitative and qualitative measurements in chemistry?
Quantitative reactions are those that use measurement or numbers; for example, 5 feet, 40 degrees, or a pH of 4.
Qualitative reactions are those that use our five senses to gather data or information; for example, the substance is blue, or feels slippery.
You can use a trick to remember this:
Quantit ative, as in quantity
Qualit ative, as in the qualities of the substance
