<p>I just said KOH as it disassociates completely in a solution. (I don’t remember it mentioning conjugate acids - even then, KOH is still stronger than any conjugate base or acid) And yes, buret.</p>
<p>Ahh Okay. I was debating between the two. I even switched it from CO3- to OH-. Except I just asked my dad (He has a Ph.D. in Org. Chem from the most competitive school in the world) and he said OH-.</p>
<p>I still say OH- :P</p>
<p>
</p>
<p>No, actually, that’s not true. The question made specific reference to Bronsted-Lowry theory, in which the hydroxide ion (and NOT the hydroxide compound) is the base. NaOH isn’t a base. OH- is the base. I assure you, OH- is the strongest base.</p>
<p>And KOH is definitely a stronger base than CO3.</p>
<p>i just want a 770</p>
<p>rockermcr u took the test?</p>
<p>Yes I did.</p>
<p>well I’m only a sophomore in regular chemistry unlike you AP chem students sigh…:(</p>
<p>I’m a junior in regular chemistry.</p>
<p>ya then i’m wrong ur like a chem genuis</p>
<p>i dont mean to be random but wat did u get on ur SAT Reasoning rockermcr u seem like a kid who would get 2380-2400</p>
<p>hydroxide (hīdrŏk<code>sīd), chemical compound that contains the hydroxyl (−OH) radical radical, in chemistry, group of atoms that are joined together in some particular spatial structure and that take part in most chemical reactions as a single unit.

Organic compounds that have the hydroxyl radical as a functional group functional group, in organic chemistry, group of atoms within a molecule that is responsible for certain properties of the molecule and reactions in which it takes part.

Most metal hydroxides are bases—they form solutions that have an excess of OH− ions and a pH greater than 7, neutralize acids, and change the color of litmus from red to blue. Alkali metal hydroxides such as sodium hydroxide sodium hydroxide, chemical compound, NaOH, a white crystalline substance that readily absorbs carbon dioxide and moisture from the air. It is very soluble in water, alcohol, and glycerin. It is a caustic and a strong base (see acids and bases ).

It is prepared by reacting calcium oxide (lime) with water, a process called slaking, and is also known as hydrated lime or slaked lime.

Magnesium hydroxide (milk of magnesia milk of magnesia, common name for the chemical compound magnesium hydroxide, Mg(OH)2. The viscous, white, mildly alkaline mixture that is used medicinally as an antacid and laxative is a suspension of approximately 8% magnesium hydroxide in water.

The hydroxides of some nonmetallic elements are acidic; the hydroxide of sulfur, S(OH)6, spontaneously loses two molecules of water to form sulfuric acid, H2SO4. Ammonium hydroxide, NH4OH, is a weak base known only in the solution that is formed when the gas ammonia ammonia, chemical compound, NH3, colorless gas that is about one half as dense as air at ordinary temperatures and pressures. It has a characteristic pungent, penetrating odor.

<p>can somone explain this i dont get it</p>
<p>What exactly are you asking though?</p>
<p>I thought the test was relatively easy, this is my first time taking it. Although, i have been taking practice AP tests since February. So anything compared to the AP test is easy, lmao</p>
<p>wat did u put for teh stronges base</p>
<p>i just don’t see how it was OH-</p>
<p>Ugh - I knew that OH was the strongest base. But I thought that since bronsted lowry meant proton acceptor, the one with a double charge would be stronger becuase it would take more protons.</p>
<p>the gas pressure about fizzing
was something about pressure decreasing ive confirmed it</p>
<p>The curve is tailored to each individual, unique test right? </p>
<p>Like top 2% should always receive an 800 regardless of raw scores?</p>
<p>800 in chem is 95% percentile.</p>
<p>Aite so shahreiudin the reason its hydroxide ion is because
Since it asks for a strong bronsted lowry base you know that its looking fro something that accepts protons really strongly. On this thread we have it decided between co32- and oh-. A way to narrow this down conclusively is as follows: A strong base doesn’t let go of the hydrogen ion or proton meaning you need to find an ion with a conjugate acid that doesn’t dissociate. how do you find an acid that doesn’t dissociate(the closer to seven you get the less an acid dissociates). Because of this you need to find a answer thats conjugate is as close to seven as possible. If you chose hydroxide ion its conjugate acid is water(remember water is amphoteric). Since water is literally the weakest acid hydroxide ion is the strongest base by the bronsted lowry definition.</p>
