Tris is a compound that is commonly used in laboratories to buffer pH. You have a stock solution of Tris that is at a 1M concentration. What volume of the 1 M Tris solution and what mass of (dry) naCl are needed to prepare 40 mL of a solution that is 20 mM Tris and 200 mM NaCl?
Two acids, each approximately 0.01 M in concentration, are titrated separately with a strong base. The acids show the following pH values at the equivalence point: HA, pH = 9.5, and HB, pH = 8.5.
Aqueous hydrobromic acid will react with solid sodium hydroxide to produce aqueous sodium bromide and liquid water . Suppose 36.4 g of hydrobromic acid is mixed with 5.9 g of sodium hydroxide.

A farmer applies 1700.0 kg of a fertilizer that contains 10.0% of nitrogen to his fields each year. Fifteen (15.0%) percent of the fertilizer washes into a river that runs through the farm.
If ammonia was added to a saturated solution of copper(II) iodate in a equilibrium with its precipitate, would the copper ion concentration increase, decrease, or stay the same
In doing the Calorimetry experiment, a student did not follow the directions exactly. How would the experiment be affected if no plot of temperature was carried out. Instead the student used the value of the water just after mixing with the metal ..
