The Ph scale can tell you if a substance is an acid a base or neutral by
a Ph scale runs from a Ph of 1-14. if a substance has a Ph less than 7 (Ph<7) the substance is said to be a an acid
if a substance has a ph greater than 7 (Ph>7) the substance is said to be a base
if a substance has a Ph equal to 7(Ph=7) the substance is said to be neutral
Wow very difficult I am so confused
Explanation:
Sand and iron fillings have the same size of particles.
It would be difficult to use a mesh to separate them. Also, sometimes , the iron filing clings well to the surface of the sand particles.
The best way to separate them is to use a bar magnet. The magnetic properties of the iron fillings will get it attracted to the bar magnet leaving the sand particles behind.

Elevated carbon dioxide mean too much acid in the blood. <span>Increase acid excretion (intercalated cells secrete H+ into tubules) and decrease bicarbonate excretion. They also make new bicarbonate to add to the plasma.</span>
