WebbCalculate pOH from pH by using the pH + pOH = 14 (at 25 0 C) Then you can calculate the concentration of NaOH solution by pOH = -log10[OH-(aq)] . Then find the required moles of NaOH by the equation of C =n/v . Here C = concentration, n=required moles, v = volume of solution. Now weight is measured by multiplying number of moles and molar mass. WebbThe pH of a solution varies from 0 to 14. Solutions having a value of pH ranging from 0 to 7 on the pH scale are termed as acidic and the value of pH ranging from 7 to 14 on pH …

WebbThe pH is given by the formula pH = -log [+] where [H+] is the concentration of hydrogen ions in moles per liter. Most common solutions have pH ranges between 1 and 14. What values of [H+] are associated with these extremes? pH = 1 [H+] = 0.1 * * 10-1 pH = 14 [H+]= 10^14 This problem has been solved! Webb23 aug. 2024 · The HH equation tells us that this will depend on the pH and the pKa of the functional group. If the pH is 2 units below the pKa, the HH equation becomes, -2 = log A/HA, or .01 = A/HA. This means that the functional group will be about 99% protonated (with either 0 or +1 charge, depending of the functional group). WebbOne way to start this problem is to use this equation, pH plus pOH is equal to 14.00. And we have the pOH equal to 4.75, so we can plug that into our equation. That gives us pH plus … north austin italian restaurant
