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.
In case of water there is equal concentration of H+ and OH- ions, so it is neutral. mean 7 is the midpoint in pH scale. pH more than 7. exact concentration of these ions and we are able to calculate their pH easily. calculate the pH of weak acids or bases which donât release all their H+ or OH- ions.
