1. Explain how to identify the concentration of vinegar in an experiment. 2. Explain how to calculate the molarity of acetic acid ( H C 2 H 3 O 2 ). Derive Ka and pKa, starting from the chemical equation for the dissociation of a strong acid (HA) in water. ...
Find the molarity of a solution that is made by dissolving 76.54g NaCl in enough water to make a 3,567 mL solution. Calculate the pH of a buffer solution prepared from 0.155 mol of phosphoric acid, 0.250 mol of KH_2PO_4, and enou...
Since HCl is a strong acid, it completely ionizes, and the pH of HCl in solution can be found from the concentration (molarity) of the H+ ions, by definition equal to 0.100 M. (The conjugate base of the acid, which is the chloride ion Cl–, would also have a concentration of 0.100...
multiply each row of the first matrix with each col umn of the s econd matrix and add all to get the first element. similarly, multiply and add the elements of the two matrices, column and row-wise, to get the elements of the produ ct of two 3×3 matrices. q5 how do we find ...
How many mL of NaOH need to be added to reach the equivalence point? If a titration of 0.5533 grams of KHP needs 25.84 mL of a NaOH solution to reach the equivalence point, what is the concentration of the NaOH? How to find molar mass from tit...
Percent error is the difference between an approximate or measured value and an exact or known value. Here is how to calculate percent error.
Converting From pKa to Ka In some tables, you may find the pKa value listed, but you may need the Ka value to plug into your equations. The mathematical operation you perform is Ka = antilog (-pKa). You solve this by raising both sides of the original relationship to powers of 10 to...
Moreover, molarity is expressed as the quotient of the number of the moles of the substance and the volume of the solution in liters.Answer and Explanation: We want to determine the mass of the substance, m, that is needed in order to...
