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.
Water is neutral and has a pH of 7.0. The pH scale has a range of 0-14. Acidity is when the concentration of hydrogen ions (H +) activity is more than pure water and is represented as 0-6.9 on the pH scale. Basicity or alkalinity is when the concentration hydrogen (H +) activity is less than pure water and is represented as 7.1 to 14 on the pH scale. See page 828 in the textbook. Draw a diagram of the pH scale below using the above information. Purpose: the purpose of this lab is to differentiate between quantitative and qualitative observations. ï· Quantitative observations are collected using measurements or numerical information.
