Design an experiment to determine the molarity of a 100 ml solution of benzoic acid. What is the molarity if pH at the stoichiometric point is 8 and the volume of base needed is twice the volume of acid being titrated? What is the molarity of the base
Using henderson hasselbalch calculate the ph of .5 L of 2.0M solution of nitrous acid, HNO2 that also contains 140g of nano2 (MM=70g/mol)
Why is it particularly important to wash the cupric hydroxide intermediate in the synthesis of cupric acetate (verdigris)? Be specific about what is being removed and why it matters.
The half-life of Plutonium-239 is 24,000 years. If 10 gms are present now, how long will it take until only 10% of the original sample remains? Round your answer to the nearest 10,000th.
Which one of the following does not react with aqueous sodium hydroxide?
