How to find molar mass from titration? What is the molarity of NaOH if it takes 40.0 mL of NaOH to reach the equivalence point in a titration with 50.0 mL of 0.2 mol/L HCL? (A: 0.25M) The point in a titration where the moles of acid are...
A titration involves the addition of a solution of known concentration (titrant) to a known volume of another solution of unknown concentration (analyte). You add the titrant slowly until the reaction is complete, at which point you can determine the concentration of the unknown solution. Titrati...
How is titration used in water testing? Titration is another way to test for pH. Basically, the tester starts with a solution he or she already knows the concentration of. The tester thenuses that knowledge to determine the concentration of an unknown solution. ...
The only way to check the solution concentration from your measurement is to calculate the density (you have both mass and volume), and find the related concentration in the density tables. Logged ChemBuddy chemical calculators - stoichiometry, pH, concentration, buffer preparation, titrations....

How do you calculate acidity from titration? How to find grams of acetic acid in vinegar solution density of 11.421 \ g? Calculate the pH of a 0.25 M HCI solution. How would the pH of a 0.25 M acetic acid solution would compare to your calculate pH for the HCI solution?
To calculate the pH of a buffer solution when base is added, the Henderson-Hasselbalch equation, pH = pKa + log (acid/base), is used. The mol of base is added to the buffer's base, and the base's mol is subtracted from the buffer's acid. These new mols are used to find the ...
I also struggled to find the moles. What moles do I find? the NaOH or HCl? I wasn't sure, but I just used the HCl. n(HCl)=0.025L x 0.5M =0.0125mol ΔH=-0.6935kJ/0.0125mol =-55.48kJ/mol Could you help me understand how to find the mass and which moles to use? Thank you...
In these subjects, they are often referred to as “acid-base reactions”, “acid-base titrations”, “ionic solutions”, and “acid-base theories”. We have identified four categories of rationales why students need to understand acid-base processes: daily life; socio-scientific; curriculum; ...
