Calculate the vapor pressure of water, in torr, above a solution prepared by dissolving 60.20 g of PbCl4 in 421.0 g of water at 343.0 K. The vapor pressure of pure water at 343.0 K is 233.7 torr.
You are on a backpacking trip and need to make a fire. You have some batteries and a piece of foil from some gum. These should be sufficient to get the fire going.
propanoic acid ch3ch2cooh has a ka of 1.34 times 10-5. a 25.00 ml sample of 0.1000 m propanoic acid in flask is
The pKa of acetic acid, HC2H3O2, is 4.76. A buffer solution was made using an unspecified amount of acetic acid and 0.30 mol of NaC2H3O2 in enough water to make 1.50 L of solution. Its pH was measured as 4.50 on a meter.
Please give reasons for compounds like silver sulfate or silver chloride to be insoluble that relate to ionic radius.
