PH and POH

• When acids are measured :

• the pH is less than 7, but the pOH is greater than 7

• the pH is greater than 7, but the pOH is less than 7

• the pH is equal 7, but the pOH is less than 7

Seawater has PH=8 , Cleaner has PH= 14 and blood has PH= 7.3 . Which one has a higher concentration of H+ ions

• Seawater

• Blood

• Cleaner

The H+ ion concentration in aqueous solution is 1.0 x 10^-8 M. What is pH?.

Is the solution acidic, basic, or neutral?

• PH = 8 ,the solution is Neutral

• PH =-8 ,The solution is acid

• PH= 8 , the solution is base

Pure water has PH= ?

• 7

• 8

• 7.2

When we use Red Cabbage pH indicator ,the color of solution was red , that mean

• solution is neutral

• Solution is Acid

• Solution is Base
