Question 1

what is pH?

Answer 1

a measure of the number of hydrogen ions in a water-based fluid

Question 2

what has a neutral pH of 7?

Answer 2

pure water

Question 3

between lower and high pH fluids, which has more hydrogen ions?

Answer 3

lower pH fluids have more hydrogen ions than higher pH fluid

Question 4

water molecules will dissociate into hydrogen (H+) and hydroxide (OH-) ions

Answer 4

H2O (water molecule)> OH- (hydrogen ion) > H+ (hydrogen ion) > H2O (water molecule)
