0.700L of formic acid-formate buffer with a pH of 3.74. How many milliliters of the two stock solutions of 1.25M HCOOH and 1.0M NaOH would you combine to make the 0.700L of buffer.
What is the molar solubility of PbI2 in water? For PbI2, Ksp=7.9x10-9. You may assume that the ions do not form ion pairs in solution. Give your answer in moles per litre, accurate to two significant figures
The rate law for a hypothetical reaction is rate=k[A]2 When the concentration is 0.10 moles/liter, the rate is 2.7 * 10-5 moles/liter second. What is the value of k?
