What is the purpose of the potassium hydrogen sulphate used...

Aqueous solutions of potassium hydrogen sulfate and potassium hydroxide react to form aqueous potassium sulfate and liquid water. How many moles of potassium hydroxide are necessary to form 0.636 mole of potassium sulfate?

No. So in potassium permanganate, we have the permanganate ion um N. 04 minus, which has an oxidation state of plus seven for the manganese, and it can be reduced to form Manganese two plus, which has an oxidation state of plus two. And this reduction is a very effective um chemical reaction for titillation Because IMN 04- is going to be a deep purple color. And upon the formation of MN two plus, it forms pink, pale pink color, so you can visually see the reduction happen and basically it's it's own indicator in a situation where we use colour change to indicate that the process has been completed.

At the magical uses off our potassium permanganate. So it potassium permanganate is used as a medication for a lot of skin conditions. So this includes infections off foot in Pattaya go as well. A superficial wounds, dermatitis as well as tropical ulcers. And so the root of his administration off our potassium permanganate is topical on. By this, I mean that is just applied it directly to the skin as a sort of cream on door lotion.

The question you have is what is the hydrated hydrogen ion And why is it important to help explain that? We're going to start with an example of a strong acid dissociating in water. In this case we're going to do hydrochloric acid. Hydrochloric acid fully dissociates in water to form two ions. This H plus and cl minus apologies for that when in solution, uh hydrochloric acid doesn't exist as hcl it exists as these two ions when in water. And specifically what we're concerned with is this H Plus, because while we consider H plus to exist often, that's not the way it actually interacts with water. So, to explain this further, we're going to show the formation of the hydrated hydrogen ion, which is also known as hydro knee. Ums you might hear it referred to as hydro knee. Um So each plus when it's sitting in a solution has a positive charge. And when it's in water, what we have to remember from water is that water has partial charges, Its polar. So I'm gonna draw that out here. So we've got water. Yeah. And water has a partial positive charge on the ends of both the Hs and a partial negative charge near the oxygen. And so they have di polls going on here. So this partial negative charge at the oxygen can interact over here with the positive charge of our hydrogen. So we end up with what they call the hydro knee um or hydrogenated hydrated hydrogen ion called hydro medium, where we see this interaction and it's sometimes written like this. Um you would note that I did not include electrons for this, but it does exist. So this is the hydrated hydro nia my on high hydro Nehemiah or hydrated hydrogen ion. And what's happening here, as we see that interaction from the negative charge up here on our oxygen, interacting with that positive charge on the H. To form this. And this is a better representation of how the H. Plus protons are interacting in solution with water. Um scientists don't really know how many of our hydrogen protons exist as this hydro nia. My on, however, this is a better representation of how water can be acidic. As we see these increase this positive charge. Things occurred because of this interaction. So that's the higher journey um ion or also the hydrated hydrogen ion. And the reason it's important is because it gives us a better understanding of why water gains is acidic properties and how hydrogen protons are hanging out in solution. Yeah.

The complete explanation for the answer is dead. The ballast equation for the formation of petition Self it from quotation hydrogen sulfate and port ation hydroxide is as follows that catches off four plus. Okay. Oh, Edge which gives get us 1/4 place esto here. The mole to mole relationship between K Wedge and K two s 04 from the balance equation is as follows that one mole K O h is equal toe one mole Kato s 04 her The to conversion factors from the mold to mold relationship between K. O. H and K two s 04 are as follows that one mole Ko hoh divided by one mold que two s 04 and one more k two s 4.1 more keywords her the desired conversion factor tow obtain malls off a watch from malls off Kato s A four will be as follows that one more K watch per one more k two s 04 Now they use use the desert conversion factor and 0.636 moles off case to a so forth to deter minder needed malls off a Ohh! Here we can clear this that you're a 0.636 small off K two s 04 multiplied by one more off the vegetable by one more off us off or equal to 0.636 small cable at you. Therefore, the required amount off a wedge is 0.636 mm More. This was a complete explanation off desperation in detail. Please go through this.
