WebApr 11, 2015 · pH = -log (hydrogen ion activity). and "pH of 7.6 M HCl is about -1.85 (not -0.88)" So how far off is -log (5) = -0.69 from the real answer? From this table of activity coefficients 5m HCl has an activity coefficient of 2.38, so activity is 11.9, which yields pH = … WebProcedure. First, express the percent of solute as a decimal: 5% = 0.05. Multiply this decimal by the total volume: 0.05 x 1000ml = 50ml (ethylene glycol needed). Subtract the volume of solute (ethylene glycol) from the total solution volume: 1000ml (total solution volume) - 50ml (ethylene glycol volume) = 950ml (water needed) earl gardner pianist

WebpH scale: pH is normally measured in a range of 0-14. [Due to mathematical definition and calculation it is possible to get negative pH and pH above 14] If pH < 7 then it is acidic solution. If pH > 7 then it is basic solution. If pH = 7 then it is neutral. WebI was preparing a phosphate buffer and adjusting its pH to 7.2 from 9.0 by adding monobasic phosphate. In the beginning, it started to decrease fast but then, it went slowly (it was about pH=7.6).

WebVarious chemical compounds can alter the concentration of H + in a solution, which results in a change of pH. An acid is a substance that increases H + concentration and reduces pH.
