An approximately 0.1 M NAOH solution is made by adding 4.0 g of solid NaOH to 1000 ml of water. The precise concentration of the solution is determined by titrating the NaOH against portions of a weak acid, potassium acid phthalate (KHP) obtained from the National Bureau of Standards and certified as being 99.99% pure. The KHP samples are weighed by difference on a balance. How would the calculated NAOH concentration be affected (in comparison with the true concentration), if: (does it become greater, smaller, or unchanged) 1. The KHP was not dried prior to weighing? 2. The balance always read high, but in proportion to the weight recorded?
