A flask contains 300mL of 0.12M phosphate buffer that has a pH of 7.2. What volume of 0.2M HCl should be added to drop the pH to 6.7
a large cylinder of He gas,such as that used to inflate balloons,has a volume of 25.0 L at 22c and 5.6 atm. How many moles of He are in such a cylinder
When a basic solution of Cr(OH)4- ion is slowly acidified, solid Cr(OH)3 precipitates out and then redissolves in excess acid. If Cr(OH)4- exists as Cr(H2O)2(OH)4-, write equations that represent these two reactions.
