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 scale. The term pH symbolizes the hydrogen ion concentration in a solution (for example, what proportion of a solution contains hydrogen ions). The pH scale goes from 1â14. A pH of 7 is neutral, meaning that the amount of hydrogen ions and hydroxide ions in a solution are equal. For example, water has a pH of 7 because when water breaks up, the split is equitable into one hydrogen ion for every hydroxide ion.
