Answer to: Which of the following is a strong acid/base? i. A solution with pK_a = 4.74 or pK_a = 2.5. ii. A solution with K_b = 1.8 times 10^{-5}...
What is the conjugate acid of HSO4-? Hydrogen Sulfate: Hydrogen sulfate is a polyatomic ion with the formula HSO4-. The negative charge on the ion tells us it has one extra electron. Hydrogen sulfate is also a conjugate base. Answer and Explanation: ...
To test this hypothesis, additional vacuole transport experi- ments were performed under conditions that ensured a drastic reduction of the driving force for proton-coupled exporters (Fig. 4c). NH4þ , a proton gradient dissipater, was added to the external buffer, whereas Mg-ATP was omitted ...
Which of the hydrogen atoms shown below is more acidic? Explain your answer. 1. Hydrogen atom in is more acidic. a) A. b) B. 2. The conjugate base of this molecule is a substituted a) cyclopenta Which of the following solutions is the least acidic? a. 1.0 mol/L HCl(aq) b. 1.0...
Hint:Tosylate is the anion formed from tosylic acid. The other name of tosylic acid is p-toluenesulfonic acid. The conjugate base of tosylic acid is tosylate. It is toluene with a sulfonate group attached to it on the fourth position. ...

Therefore, because the pKa of water is lower than ammonia, it is a stronger acid the ammonia and will donate protons to the ammonia base. This reaction leads water to become the conjugate base OH- and ammonia to become the conjugate acid NH4+. Interestingly, this is why ammonia is a caus...
conjugate base for the buffer. The buffer equilibrium is HC2H3O2 H + + C2H3O2 – acetic acid acetate ion For acetic acid, Ka(HC2H3O2) = 1.8 x 10 -5 so pKa = -log10Ka = 4.74. Thus when [HC2H3O2] = [C2H3O2 – ], pH = pKa = 4.74. 1 2 Basic Buffers In a basic buffer both...
Conjugate Bases: In Acid-Base theory, a conjugate base is a base with the general formX−that can gain a proton to become an acid with the general formHX. Therefore, if a reaction starts with an acid that donates its proton, one of the products...
