The pH scale depends on the value of Kw. What would the pH of neutral water be if the Kw was 5.54 x10-15? IMPORTANT: When entering your answer: • Enter the number only (no units) • Do not leave any spaces • Use a leading zero before the decimal when necessary Report your number to 3 decimal places (regardless of the significant figures) Correctly round your answer to the 3rd decimal place (allowed margin of error is only + 0.001, so always use un- rounded numbers in your calculations) Examples: 0.123 or 9.876

Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory as a primary standard. It has the formula KHC8H4O4. This is often written in the short-hand notation as KHP. If 25.0mL of a potassium hydroxide solution are needed to neutralize 2.26g of KHP, what is the molarity of the potassium hydroxide solution? Potassium hydrogen phthalate sometimes called potassium biphthalate, as shown on this bottle is an acid that is convenient to store and use because it is a solid.
