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.
Because the ratio of hydrogen and hydroxyl ions remains the same, the acidity of water does not change with temperature 28. Instead, the entire pH range shifts, so that neutral water will have a value other than 7. Pure water will remain neutral at 0Â°C (pH is 7.47), 25Â°C. (pH is 7.00) or 100Â°C. (pH is 6.14).
