If 3.50 mL of vinegar needs 45.0 mL of 0.150 M NaOH to reach the equivalence point in a titration, how many moles of NaOH were used in the titration? Calculate the amount of KHP required for 30 mL titration vol
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. Titratio...
when the acid has been neutralized. At this point, adding more base causes the pH to rise rapidly. After equivalence has been reached, the slope decreases dramatically, and the pH again rises slowly with each addition of the base. The inflection point, which is the point at which the lower...
What happens at the equivalence point during a titration? Calculate the molarity of the acetic acid in vinegar, if a 500ml sample of the vinegar requires 43.50 ml of 0.105 M NaOH to reach a phenolphthalein endpoint in a titration. What is the indicator in the titration with permanganate soluti...
Distinguish between the terms end point and equivalence point and give an example. Explain whether each of the errors below would cause your calculated K_{sp} value to be higher or lower than the tabulated value. Assume you are using method (1)...
50 M HCl calculate pH at HALF- EQUIVALENCE POINT (i.e. when [CH3NH2] = [CH3NH3+] )There are 3 steps to solve this one. Solution Share Step 1 Molarity of of methyl amine (CH3NH2) solution =1.0M Volume of methyl amine ...
Using the given information, calculate for the moles of the weak acid in the solution and the moles of the strong base that has been added. Remember: molarity(M)=molesvolume(L) Step 3: Even though the strong base is completely consumed when reacting with weak acid to form...
achieving the double objective of providing to thermodynamics a theoretical foundation and a systematic procedure to calculate its quantities, which otherwise can only be obtained from experiments , e.g., the value of the heat capacity, or from approximate phenomenological laws, e.g, the van der ...
How to Calculate The Phi Function A simple (but a little tedious) way to perform the calculation by hand is: Write down all of the numbers in the set. Delete the numbers that share any common factor greater than 1. As an example, let’s say the number in the set is n = 30. ...
There are several counterarguments regarding the efficiency and long-term benefits of economic stimulus plans. Some theorists believe that an economic stimulus can actually delay or prevent a private-sector recovery from the actual cause of a recession. According to this viewpoint, it is misguided ...
