Calculate the Ka of an acetic acid solution if the pH is 4.76 and concentration is 176 mM. How can you determine dominant species given pKa? A solution of acetic acid (pKa = 4.75) has a pH of 6.75. The ratio of the acid to the conjugate base is. Explain your answer. ...
In order to calculate the pOH, take the negative log of the hydroxide ion concentration. To find the pH, simply subtract pOH from 14. What Do pH and pOH Measure? When a strong acid is added to water, there is an increase in the amount ofhydronium ions(H3O+). This is because the hy...
Alkalinity is the ability of a solution to neutralize an acid to the equivalence point of calcium carbonate. It is not to be confused with basicity. In an academic setting, alkalinity is measured in milliequivalence per liter, and in commercial applications it is given in parts per million. A...
The pH scale ranges from 0 to 14, which measures acidity or alkalinity levels (also known as the basicity) of any substance. You can also measure the ph balance of foods, liquids, and even the saliva in your mouth. Substances that fall below a pH of 7 are considered acidic, and those...
In the previous section, we established that solvation reduces the basicity of the Lewis base. But how does this affect the competition between SN2 and E2? By applying the ASM, we find a switch from the preferential E2 to SN2 reactivity if one goes from weak solvation in the case of (...
they’re afraid of what it’s going to find. Now, what they’ll tell you is that we’re afraid it’s going to destroy the world to make everyone afraid. Now, while destroying the world is a reasonable thing to fear in the long run, that’s not going to happen...
Given that neutral resonance structures are preferred overall, when a resonance structure absolutely must bear a negative charge somewhere,place it on the atom best able to stabilize that charge.Since, in essence, “basicity is the opposite of stability”, this is the same as saying, “put the...

We propose explicit and implicit approaches for the teaching of acid-base chemistry based on research into the history and nature of science (NoS). To supp
Litmus paper, or red and blue test strips, will tell you whether a solution is an acid or a base, but it won't give you information about the strength of the solution. Universal, or alkacid, indicator paper has a different color to match every number on the pH scale. Neutral solutions...
