A solution is made by dissolving 15.3g of HCl in enough water to make 4.70x10^2 mL of solution. Calculate the pH of the solution at 25 degree C.
what is the molar concentrations for those two. The solution volumes are additive. Thank you so much I can't figure this out and I've been looking at it for 2 hours. I need it for my lab report.
The pH of a bicarbonate-carbonic acid buffer is 8.30. Calculate the ratio of the concentration of carbonic acid (H2CO3) to that of the bicarbonate ion (HCO3-).
