<h3>What is pH?</h3>
The term pH, which originally stood for "potential of hydrogen" (or "power of hydrogen"), is used in chemistry to describe how acidic or basic an aqueous solution is. Lower pH values are summarized for acidic solutions (solutions with higher H+ ion concentrations) than for basic or alkaline solutions.
The pH scale is inversely indicates to the concentration of hydrogen ions in the solution and is logarithmic.
⇒pH = -log(
)
Acidic solutions are those with a pH below 7, and basic solutions are those with a pH above 7, at a temperature of 25 °C (77 °F). At this temperature, solutions with a pH of 7 are neutral (e.g. pure water). The pH neutrality relies on temperature, falling below 7 if the temperature rises above 25 °C.

Copper II sulfate solution is blue.
We imagine a piston cylinder and a solution of gas and water. Molecules are in constant random motion and some of the gas particles are in the vapor phase while some in the liquid phase. At a specific volume, molecules move freely. However, when the piston is moved down, increasing the pressure, some of the molecules in the vapor are pushed down to the liquid phase in order maintain equilibrium thus increasing solubility <span />
Answer:
The sole purpose is to rejuvenate the column. After long use the ions bound in the permutit column will get washed away. This can be replaced by washing the column with NaCl.
The answer would be 1.25g
Since you have 10g of a substance, you would need to half your substance by doing this: 42/14=3
Once doing this you would half your substance 3 times like so:
10/2=5
5/2=2.5
2.5/2=1.25
