pH Calculations: Problems and Solutions - SparkNotes
What is the pH of a solution of 0.36 M HCl, 0.62 M NaOH, and 0.15 M HNO 3? Hydrochloric acid and nitric acid are strong acids, and sodium hydroxide is a strong base; these all dissociate completely.
Since there is both acid and base we will assume a 1 mole acid:1 mole base ratio of neutralization. There is more base than acid so the leftover base is what will affect the pH of the solution. 5) What is the pH of a 6.2 x 10-5 M NaOH solution? 6) A solution with a H+ concentration of 1.00 x 10-7 M is said to be neutral. Why? log[OH-]-1 7.000.

pH Problems
Calculate [OH−] in a solution in which [H+] is 3.72 × 10−3. What is the pH of a solution if [H+] = 5.31 × 10−9? Example 3: Calculate [H+] for a solution having a pH of 1.57. On old-style calculators, you’ll type this after entering the number.
How to Calculate pH – Formula and Examples - Science Notes …
Jul 21, 2020 · pH Calculation Formula. The formula to calculate pH is: pH = -log[H +] The brackets [] refer to molarity, M. Molarity is given in units of moles per liter of solution. In a chemistry problem, you may be given concentration in other units. To calculate pH, first convert concentration to molarity.
Part 1: Fill in the missing information in the table below. ACID or BASE? Part 2: For each of the problems below, assume 100% dissociation. Write the equation for the dissociation of hydrochloric acid. Find the pH of a 0.00476 M hydrochloric acid solution. 2. Write the equation for the dissociation of sulfuric acid.
The important thing to remember for all of these problems is that pH = -log [H+], and that [H+] is equivalent to the molarity of acid present in a solution. When the pH is less than 7, the solution is acidic, when the pH = 7 it is neutral, and when it is greater than 7, it is basic.
