can anyone help me on my chemistry problem. i need a merck index to solve this. i have a PH of 10.7 and the nearest solution that is near to it is 10.32. The solution that is 10.32 is NaHCO3. i subtract both of them to get the ratio of log (HA)/(A-). i took that value to the 10th power to get rid of the log and got a value of .417M/1M. then i multiply that by the molar mass which is 84 g/mol to get rid of the moles and divide by 1000 to have it in g/mL. which is .035028 g/mL. now i need to know if this is soluble under this amount of mL. can any chemists help me.
