Determine the pH
1. [H3O+]=9.0×10^−9M
Determine the total alkalinity in mg CaCO3/L given the following: a)[HCO3-] =0M ,[Co3^2-]=0M ,[OH-]=1.0*10^-5M ,[H3O+]=1.0*10^-9M b)[HCO3-] =0.0100M ,[Co3^2-]=0M ,[OH-]=2.0*10^-6M ,[H3O+]=5.01*10^-9M c)Convert a and b to meq. I already aksed this question once on Cheg, and it was not explaned so i am re-asking in hopes for a better responce. A step by step solution would be greatly appreciated.
