Learn how to calculate the pH of a strong base solution, and see examples that walk through sample problems step-by-step for you to improve your chemistry knowledge and skills.
I learned at some point how to do pH-calculations, but my teacher was so bad, that I never really understood it and now I don't manage to calculate it myself anymore Maybe someone here could help me with the following?Have 8 liters of watery solution with pH of 7.4 and want to adj...
How do you calculate the Ph at the equivalence point of a titration? Ionic product The ionic product for a compound is the product of the concentration of the ions in a solution. For exampl{e, for the dissociation of NaOH in water, the ion product would be {eq}[Na^+][OH^-...
How to calculate concentration of NaOH in titration? Acid-Base Titration: Titration is an analytical technique used in chemistry that allows for the determination of an unknown quantity or a concentration of an analyte using a known concentration of a titrant. A titrant is a solution that reacts...
It says to assume 1mL solution = 1g solution Is this referring to the solution or just the water? If it is referring to the solution, would the mass be 75.0g? q(soln)=m(soln)cΔT =75.0 x 4.184 x (27.21-25) =693.5J =0.6935kJ ...
I'm doing the exercises of Introduction to Data Mining, and got stuck on following questions about decision tree: Training Testing Decision tree The question asks me to calculate generalization error rate by using optimistic and pessimistic approaches, and the answers are 0.3 and 0.5 res...

Learn how to calculate initial concentrations of a solution by determining the number of moles in each liter.
Here ishow to calculate how much water you should drink a dayfor both health and weight loss benefits. Your weight:The first step to knowing how much water to drink every day is to know your weight. The amount of water a person should drink varies on their weight, which makes sense bec...
Liters of solution = mL of solution x (1 L/1000 mL) Liters of solution = 750 mL x (1 L/1000 mL) Liters of solution = 0.75 L This is enough to calculate the molarity. Molarity = moles solute/Liter solution Molarity = 0.15 moles of KMnO4/0.75 L of solution ...
