pH MEASUREMENT, VERY IMPORTANT, you can't just keep adding acid!!!
If it is not right the kids eyes and sensitive areas will get all red and sore, yours too.
A very important measurement in many liquid chemical processes
(industrial, pharmaceutical, manufacturing, food production, etc.)
is that of pH: the measurement of hydrogen ion concentration in a
liquid solution. A solution with a low pH value is called an "acid,"
while one with a high pH is called a "caustic." The common pH scale
extends from 0 (strong acid) to 14 (strong caustic), with 7 in the
middle representing pure water (neutral):
pH is defined as follows: the lower-case letter "p" in pH stands for the negative common (base ten) logarithm, while the upper-case letter"H" stands for the element hydrogen. Thus, pH is a logarithmic measurement of the number of moles of hydrogen ions (H+) per litre of solution. JUST use the test stips, too easy
