From le Since KHT is a weaker base than NaOH, its K a will be smaller than NaOH's K b , making its conjugate base's K b higher than Na + 's K a . In spite of the favourable climatic conditions for the production of varieties of delicious fruits in such countries, continuously high tempemtures shorten the shelf-life of most fruits and fruit products. Aqueous solutions of both of these substances must be standardized; that is, their concentrations must be determined by titration. Precaution: 1. What are the units used for the ideal gas law?
