WebAnswer (1 of 3): Here is the answer. You can get pH of 0.01N NaOH by two processes: Don't forget to upvote and follow me WebFeb 10, 2024 · There is only 1 OH -, so the number of equivalents is 1. Look at a periodic table and find the sum of the atomic masses of the Na, O and H in your formula: Na = 22.99; O = 16.00; H = 1.01. To sum, 22.99 + 16.00 + 1.01 = 40.00 g/mole Eq = 40.00 / 1 = 40.00 g/eq The gram equivalent weight of NaOH is 40.00 g/eq. Normality Equation

WebJan 30, 2024 · Step 4: Solve for the pH after a bit more NaOH is added past the equivalence point. This will give us an accurate idea of where the pH levels off at the endpoint. The equivalence point is when 13 mL of NaOH is added to the weak acid. Let's find the pH after 14 mL is added. Solve for the moles of OH-\[ (14 mL)(0.1M)=1.4\; mmol OH^-\] WebSep 12, 2024 · This series of calculations gives a pH = 4.75. Thus the addition of the base barely changes the pH of the solution. (c) For comparison, calculate the pH after 1.0 mL of 0.10 M NaOH is added to 100 mL of a solution of an unbuffered solution with a pH of 4.74 (a 1.8 × 10 −5-M solution of HCl). The volume of the final solution is 101 mL. simply kinder alphabet crafts
How to Calculate the Normality of NaOH Sciencing
WebAug 18, 2015 · A 100 ml H C l solution has a pH of 3.7. You want the solution to be of pH 4.5. You have a solution of 10 M N a O H. How much N a O H do you need to add to to the 100 m l solution of H C l to get a pH of 4.5? I firstly calculated the concentration H C l in 100 m l solution = 10 − 3.7 = 2.0 × 10 − 5 m o l H C l per 100 m l.
