Get PriceWhereas the pH values of the kaolin suspensions were nearly the same after the sedimentation experiments the pH values of corresponding bentonite suspensions generally increased by 2 Maximum pH increase after sedimentation was observed for the boric acid containing bentonite suspension from pH 4 to 7 148
Get PriceAt room temp the pKa is 4 76 so the Ka is 1 737X10^ 5 Ka= [A ] [H ]/ [HA]= [Conjugate base] [Acidity]/ Associated Acid]= [x]^2/ [3 33 x] Solve for x and you get 7 599X10^ 2= [H] Log10 of that gives you pH=2 119 For 12 5% pH=2 22 For 10% pH=2 26 For 7% pH=2 34 For 5% pH=2 42
Get PriceThe equilibrium equation yields the following formula for pH pH = log 10 [H ] [H ] = 10 pH In other words pH is the negative log of the molar hydrogen ion concentration or the molar hydrogen ion concentration equals 10 to the power of the negative pH value It s easy to do this calculation on any scientific calculator because more often
Get PriceObjects that are not very acidic are called basic The scale has values ranging from zero the most acidic to 14 the most basic As you can see from the pH scale above pure water has a pH value of 7 This value is considered neutral—neither acidic or basic Normal clean rain has a pH value of between 5 0 and 5 5 which is slightly acidic
Get PriceIt can be seen from Table 8 that the F value of temperature and pH is 2 94 and the P value is 0 1087 indicating that the interaction between temperature and pH is not significant
