The pH scale is a measurement system that indicates the concentration of Hydrogen ions also called Protons.
Metric
All metric units of linear measurement are multiples or sub-multiples of the meter.-- nanometer = 10-9-- millimeter = 10-3-- centimeter = 10-2-- meter-- kilometer = 103..etc.
This light serves a dual purpose on most cars. - Indicates that the handbrake has been applied - Indicates that there is a problem with the braking system The latter requires one to have their brake systems checked by a professional.
SI is the acronym for System Internationale. SI hold the degree Celsius to be the basic unit when it comes to the temperature measurement.
This light indicates a problem with your vehicle's charging system, and means that your car is running strictly on the energy available in the battery...and that won't last long. Best to have your charging system checked at your first available opportunity. For more tips, see the info on my bio page. Hope this helps!
It determines how acidic it is.
The pH system is used to indicate the concentration of hydronium ('H+') ions in solution. It is governed by the equation pH = -log[H+]
the pH scale. as the pH of the solution decreases (below 7), the concentration of H+ ions increases. as the pH of the solution increases (above 7), the concentration of H+ ions decreases. (if the pH is 7, the solution is neutral).

pH
Chemists devised a measurement system called the pH scale to indicate the concentration of hypotonic ions in solution. Therefore the higher the pH scale gets the more persistant it is.
pH scale is used to indicate the concentration of hydrogen ions in a solution. It is a measure of the acidity or alkalinity of a solution, with lower pH values indicating higher acidity and higher pH values indicating higher alkalinity. The pH scale ranges from 0 to 14, with 7 being neutral.
it makes up of molecules that have an even concentration throughout the system.

The amount of salt in reverse osmosis system brine can vary depending on the concentration of the salt solution used for regeneration. Typical concentrations range from 5-10% salt by weight. To calculate the exact amount, you would need to know the volume of brine produced by the system and the concentration of the salt solution.
