The wavelength was set to 220 nm, and the temperature step was set to 1 °C/min in the range of 10–95 °C. The measurements were performed using a 1 mm path length cuvette.
WebWhat is the concentration of [H+] in molars, millimolars, and micro- molars for a solution of pH 5? 4. If you mix 10 mL of a 0.1 M HCl solution with 8 mL of a 0.2 M NaOH solution, what will be the resulting PH? 5. If a weak acid, HA, is 3% dissociated in a 0.25M solution, calculate the K, and the pH of the solution. WebSince the pH scale is logarithmic, not linear, a solution of pH 1 would have ten times (not twice) the [H+] that a solution of pH 2. Likewise, a solution of pH 12 would be 10 times more alkaline than a solution of pH 11. pH Calculations Involving HCl Solutions 1. Given the Wt% of an HCl solution, what is its theoretical pH value?
