Use the table to answer the questions below. The brackets,[], indicate concentrations in the equilibrium mixture.

(table is not available to copy)

a. Describe how the $\mathrm{H}^{+}$ concentration for Solutions $1,2,$ and 3 relates to the solution molarity.b. Explain how the value of $K$ depends on the specific acid and the solution molarity.c. Explain why $\left[\mathrm{H}^{+}\right]=\left[\mathrm{A}^{-}\right]$ .d. For formic acid and acetic acid, describe a particle view of the equilibrium mixture.e. Determine the pH for all five solutions.f. If spilled, Solution 3 will cause more harm than Solution $5 .$ Use this information to explain why pH, as opposed to molarity, is important in determining how dangerous an acidic solution is.

using the table provided less. Answer the following questions for a describe how the H plus hydrogen ion concentration for solutions +12 and three relate to these solution. Malaria T. So for in acid, you've got a cheek a plus. Siege to a home produces three, all plus and a minus de grader. The H plus concentration, the stronger the acid. Therefore he greater the X Plus concentration creator. The solution morality for be explain how the value of K the equilibrium constant depends on the specific asset and the solution. Molar ity for strong acids, 309 is readily formed and value of the equilibrium constant K is higher for stronger acids, then weak acids. The Librium constant K depends on the concentration of products divided by the concentration of reactant. Since using our equilibrium from part A. This would be a three old plus a minus over the concentration of each. For C, explain why H plus is equal to a minus. So let's look at a model product weak acid again, this is going to go back to the equilibrium in part a. So one more of H A associates to form each plus and a minus, therefore concentration of eight plus secrets of the concentration of a minus for the supplies for both strong and weak assets. Still, for a strong acid, Thea acid is equal to the H plus sequel to the A minus. So all three of them are equal for a weak acid. The H A is much greater on the H plus, but the H plus is still equal to the A minus for D, determined for formic acid and acetic acid, A particle view of the equilibrium mixture. So Okay, yes, for formic and acetic acids, the que value it is very small, which indicates that most of the acid exists in and undiscussed C ated form. And very little, uh, H plus and a minus are formed. So this would be so if we had the either formic acid or acetic acid, we'd have lots of h A because we'd have the unassociated asset present. Uh huh. And we may have very small amount of who should go. H 30 plus all right. Each plus h plus a minus a minus. So that may be what it looks like for e determine the ph of all five solutions. So we're told. That's, um we're told the H plus in concentrations. We confined the pH full for nitric acid a general three ph seek, with a negative log of the H plus signs at 1.0. So the pH here is equal to zero, and we're going to do this to sig figs 0.0 for nitric acid. That solution one So solution. One solution to is also nitric acid. P H is equal to negative log of 0.50 This is equal to 0.30 and for a solution. Three. We also have a Channel three. The pH is equal to negative log 10 This is equal to 1.0 precision four. We have nitrous acid. Each have two in the P H is equal to negative log 0 to 2. This is equal to ph of 1.66 And for the solution five. We've got Bonzo Gas ID, which is C six h five C O. H. Ph sequel. The negative log 0.79 This is equal to 2.10 and lastly for F. If spilled, Solution three will cause more harm than solution. Five. Use this information to explain why pH as to, as opposed to mill Aridjis important determining how dangerous and acidic solution is. So the strength oven acid depends on the equilibrium constant but not on the initial polarity. H and 03 is a strong acid, so it causes more harm even at low concentrations, as it can readily release age plus science. Wow, the Zodiac acid is less harmful than H and 03 Even higher concentrations as it can on Lee partially release age plus science due to the fact that Benzo a kassid, is a weak acid.
