Answer: A solution that is a 4 on the pH scale is a (a) weak acid.

The pH scale is a universal measure of how much acidic or basic any substance is. The scale of pH ranges from 0 to 14 with 7 in middle being neutral i.e. neither acidic nor basic. Substances with pH less than 7 are considered to be acidic and more than 7 are considered to be basic. Strong acids have pH less than weak acid while strong bases have higher pH than weak bases.

Substances or solutions that have pH 0-3 are highly acidic, 4-6 are weakly acidic and pH of 7 is neutral solution while pH of 8-11 are weakly basic and 12-14 are highly basic.

Where does the oxygen we breathe come from?
Zarrin [17]

Answer:

Scientists agree that there's oxygen from ocean plants in every breath we take. Most of this oxygen comes from tiny ocean plants – called phytoplankton – that live near the water's surface and drift with the currents. Like all plants, they photosynthesize – that is, they use sunlight and carbon dioxide to make food.
