- 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?

- Beyond the Course: Your beverage company is branching out from added sugar in their beverages to make a drink where the main ingredient is fresh-squeezed orange juice, called Beverage C. Yum! The beverage will still be subjected to the same taxes as Beverages A & B, so determining sugar content is still vital. Suggest a method of reliably examining the sugar concentration in each batch of Beverage C. Some considerations to address: Do you want to measure the same property for Beverage C as you did for Beverages A & B? ● Can you use the same calibration curve as you did for Beverages A & B?
