A 3.575g sample of a monoprotic acid was dissolved in water. it took 22.67ml of a .1453 M NaOH solution to neutralize the acid. what is the molar mass of the acid
The molar mass for NaCl and water are 58.443 g/mol and 18.015 g/mol, respectively. Calculate the partial molar volumes for NaCl and water in a 0.35m solution.
Decide whether or not each of the following metals dissolves in 1M HCl. For these metals that do dissolve, write a balanced redox reaction showing what happens when the metal dissolves.
Now take another 37 mL of the 0.50 M pH 6.83 buffer and add 1.3 mL of 1.00 M NaOH. Using steps similar to those above, calculate the new pH of the solution.
