3 Acid-base titration: Calculate pKa with only three values given 1 Diluting a sample of weak base before titration. What happens to equivalence point pH of diluted vs undiluted? 1 Calculating pH when weak base is added to an strong acid 0 Finding the pH of a mixture of weak...
the pH you desire: activity-correct back to the required [H+], plug that in along with the Ka (given) and Kw (we're taking a constant at 1*10-14mol2dm-6I assume) and either Ca or Cs, depending on which one you know, and you can find the other one required to get your pH...
The pooled odds ratio for UTI in non-Black children was 1.77-fold higher (95% CI, 1.08-2.90) than in Black children. The I2 statistic was 58%, indicating significant heterogeneity. Meta-regression was of limited utility given the small number of studies. However, the study by Hsiao et ...
PROBLEM TO BE SOLVED: To provide a wastewater treatment apparatus wherein the SS, turbidity or see-through degree and pH of wastewater and the MLSS and pH of a mixed liquid in a reaction tank are measured using the same sampling device, and the control of a necessary air amount, the load...
If the pressure and mean temperature are given, the apparent viscosity and density can be calculated from equations (2) and (3), respectively. 3.1 Pressure calculation It has been known that the film thickness in an EHL contact is the sum of the elastic deformation of the surfaces and the ...
