The pH of a 0.56 M aqueous solution of nitrous acid, HNO_2, is 5.03. What is the value of Ka for HNO_2? The pH of a 1.10 M aqueous solution of nitrous acid, HNO2, is 4.09. What is the value of Ka for HNO2? What is the pH of a solution that is 0.10 M in KNO...
What is equal at the half equivalence point?The half equivalence point represents the point at which exactly half of the acid in the buffer solution has reacted with the titrant. The half equivalence point is relatively easy to determine because at the half equivalence point, the pKa of the ...
One is at pKa 4.2 and the other pKa is between 7 and 10. If you have 10.0 mL of a 1.0M solution at a pH of 8.17 and you add 10.0mL of 1.0M HCl which changes the pH to 4.2 what is the second pKa? I tried working this problem out a few different ways and keep getting ...
Molar mass is the mass of one mole of a substance. We determine the molar masses from values on the periodic table. Answer and Explanation: Before we can sum all of the molar mass of the elements in acetic acid we need the chemical formula of acetic acid. Acetic acid's chemical formula...
pKa is the measurement of acidity or basicity of achemicalorfunctional group. The acidity or basicity of a chemical or functional group can be defined in two ways: The ability to accept or donate a proton. The ability to accept or donate a lone pair of electrons. ...
