Explanation / Answer

1.why do acids and bases conduct electricity?

Acids and bases form ions when dissolved in water(H+/H3O+ or –OH,respectively). These ions move freely through the solution, andmoving charges (ions) comprise a current.

2.which conducts electricity vetter, HMnO4 or HF?

HF is a weak acid, so dissociates into ions (H+ and F-) only toa small extent; mostly undissociated/neutral HF molecules arepresent in the solution. HMnO4 is a much stronger acid,so forms H+ and MnO4- ions to a large extent. More ions mean morecharged particles moving about so larger electric currents can besupported.

3.name 3 weak acids and describe what they are used for.

Acetic, hydrofluoric, carbonic Acids (and of course many manymore). Acetic acid is vinegar (used in salad dressings) and acommon organic reactant in creating other organic compounds

Hydrofluoric acid etches glass

Carbonic acid dissolves marble/limestone (causes erosion), givessoda pop its kick, traps CO2 from the atmosphere inwater (e.g., the ocean)

4.are organic acids weak acids?

Organic acids are classed as weak acids, acetic acid being aboutthe strongest of them. The “acid” hydrogen does notbreak off the organic acid group to a large extent (compared to“strong” acids, like HCl, where ~>99% of theH’s dissociate into H+)

5.why is acid rain a problem for buildings made out ofmarble?

Carbon dioxide dissolves in water to form carbonic acid whichdissolves (reacts with) marble/limestone (causes erosion)

6.another term for basic is _______.

Alkaline

7.what is the difference btw Bronsted-Lowry Acids and Bases andArrhenius Acids and Bases?

8.What is a dissociation constant?

Some substances, when they dissolve, break apart intoions. The process is called “dissociation”, anddissociation occurs is quantified by a number called the“dissociation constant”. The number is unique forevery substance, and quantifies the fraction of dissolved moleculeswhich react and break apart into ions.

By definition, if the balanced chemical equation is

         i AB(molecule)  <-->  j A+ (apositive ion) + k B- (a negative ion)

where i, j, and k are coefficients in the balanced chemicalequation for the dissociation, then the “dissociationconstant” is the mathematical quotient

[concentration of A+ ]j [concentration ofB-]k

                         [concentration ofAB]i

If the “dissociation” creates more than two ions onthe product side, then there would be more than two concentrationsin the numerator (each raised to the power of the correspondingcoefficient)

What makes chemical computations possible is the fact that thisquotient, unique and measurable for every substance, does notdepend on the concentrations. Whatever they are, they willchange until their quotient equals the “constant”value, and then they stop changing. It’s amazing
