The red, green and blue use 8 bits each, which have integer values from 0 to 255. This makes 256*256*256=16777216 possible colors. RGB â¡ Red, Green, Blue. Each pixel in the LCD monitor displays colors this way, by combination of red, green and blue LEDs (light emitting diodes).
At a neutral pH of 7 (pure water), the concentration of both H+ ions and OH-ions is 10â»â· M. Thus the ions H+ and OH-are always paired â as the concentration of one increases, the other will decrease; regardless of pH, the sum of the ions will always equal 10â»Â¹â´ M Â².
The pH of pure water (H20) is 7 at 25oC, but when exposed to the carbon dioxide in the atmosphere this equilibrium results in a pH of approximately 5.2. Because of the association of pH with atmospheric gasses and temperature, it is strongly recommended that the water be tested as soon as possible.
