Which of the following acids will have the strongest conjugate base.

. A HClO3 B HClO4 C HCl D HClO E HClO2. Which of the following acids has the strongest conjugate base. HCN Ka 62 x 10-10.

A salt solution can be acidic basic or neutral. Which of the following acids will have the strongest conjugate base. For instance HCl is a strong acid and hence it is a good proton donor.

Given the following acid dissociation constants which acid has the strongest conjugate base. The hydronium ion is the strongest acid that can be found in aqueous solution. You can calculate Kb for each of the acids listed.

Is oh a weak conjugate base. -Hence C H 3 C O O will be the strongest conjugate base because it has been formed from the weakest acid C H 3 C O O H. Which of the following acids will have the strongest conjugate base.

Strong acids always have a weak conjugate base. The weakest acid is HClO. Dihydrogen phosphate ion K a 62 x 10 -8 c.

H 3 C O O H C H 3 C O O H Strong conjugate base has a weak conjugate acid. Specially with the first one. HIO3 Ka 017.

The ethnic acid acetic acid is considered as a weak acid because it does not releases all of its hydrogen in water. This also means that it has the weakest conjugate base. D The conjugate base of a very weak acid is stronger than the conjugate base of a strong acid.

Asked Jun 23 2017 in Chemistry by LateNightBacon. A HClO B HClO 4 C HClO 2 D HClO 3 E HCl ANS. Remember it is a strong acid too.

The conjugate base of a strong acid is itself a strong base. Strong acids are very concentrated acids. Thus Cl- ion should have a weak base.

Hence its conjugate base is strongest. In other words the weaker the acid the stronger the conjugate base ie. Among both of them acetic acid is the weakest acid and so it will form the strongest conjugate base.

All acids have H atoms bonded to electronegative oxygen atoms. H2SO4 HCl HCN NaI HNO3. Consider the Ka values for the following acids.

Oddly the next strongest acid is HCl. Benzoic acid K a 64 x 10 5 b. Since C H 3 C O O H is weakest acid therefore its conjugate base.

Since the water molecules formed as the conjugate acid of OH- have very little tendency to donate protons they are only very weak acids. If you go another route you can calculate Kb. Dimethylammonium ion K a 17 x 10 11 e.

Which is strongest base. Strong Acid - Weak Conjugate Base Pair. As the acidity of the acid decreases the basicity of the conjugate base increases.

Rather it dissociates partially and establishes equilibrium with its conjugate base. Correct Answer - Option 2. The HClO 4 has the most oxygen atoms so it would have to be the strongest acid.

The correct answer is Weak base. -So the correct option will be. B C H 3 C O O.

The conjugate acid of H2PO4 is H3PO4 which have one proton more than the base. The carborane superacids may be considered the worlds strongest solo acid as fluoroantimonic acid is actually a mixture of hydrofluoric acid and antimony pentafluoride. Acetic acid K a 18 x 10 5 d.

The smaller the Ka the larger Kw Ka will be and thus the larger Kb will be making it the stronger conjugate base. Strong acids produce solutions with a higher pH than weak acids. All acids classified as strong acids in aqueous solution have the same acidity in a more acidic solvent like acetic acid.

A strong Brønsted-Lowry acid is one which has strong tendency to donate a proton 3. The weakest acid must be HCN so CN- should be the strongest base. The more the acid wants to keep its proton the more its conjugate base will want the proton back.

Can someone help me with these. Please do not block ads on this website. Among HNO 3 HCl H 2 SO 4 CH 3 COOH is weakest acid.

I know how to get the conjugate base when it has a given base but if its an acid alone I cant. Strong acids are 100 ionized in water. Of the following acids the one with the strongest conjugate base is A.

The pka value for each acid is given in parentheses. Which of the following statements about strong acids is true. Kb Kw Ka.

Strong Base Weak Conjugate Acid Pair Strong Brønsted-Lowry bases include OH- CH3CO- and HO2-. However HCl can only be a good proton donor if Cl- ion has a poor proton acceptor. The bottom line is that the strongest acid has the weakest conjugate base or the weakest acid will have the strongest conjugate base.

HOCl Ka 30 x 10-8. I believe the answer is HCN it has the lowest Ka and is the weakest acid. Acetic acid 474 Ammonium ion 93 lodic acid 077 Nitrous acid 316 Lactic acid 38.

Formic acid K a 18 x 10 4. Which of the following is the strongest conjugate base. Strong acids include H 3 O HCl and HNO 3.

Which of the following acids has the strongest conjugate base. The hydroxide ion is the strongest base possible in aqueous solutions but bases exist with much greater strengths than can exist in water. Understand the relationship between the strength of an acid and that of its conjugate base.

Which of the following weak acids has the strongest conjugate base. Its a fact that weakest acids have strongest conjugate base. For example in water a strong acid like hydrochloric acid readily donates a proton to a water molecule.
