Determine whether each of the following salts will form a solution that is acidic, basic, or pH-neutral?

Al(ClO4)3-Acid
LiCl-Neutral
KClO2-BAse
C6H5NH3NO2-Acid
CH3NH3Br-Acid

KCl-Neutral
NaClO-Base
NH4ClO-Acid
Fe(ClO4)3-Acid
C2H5NH3NO3-Acid

Is this right?

I just finished answering this at the original post. I voted for NH4ClO to be basic. I explain below.

To determine whether a salt will form an acidic, basic, or pH-neutral solution, you need to consider the nature of the cation (positive ion) and anion (negative ion) that make up the salt.

1. Al(ClO4)3: This salt contains the cation Aluminum (Al3+) and the anion Perchlorate (ClO4-). Since Al3+ does not have any acidic or basic properties, and ClO4- is a weakly acidic ion, the solution formed by this salt will be acidic.

2. LiCl: This salt contains the cation Lithium (Li+) and the anion Chloride (Cl-). Both Li+ and Cl- are neutral ions, so the solution formed by this salt will be pH-neutral.

3. KClO2: This salt contains the cation Potassium (K+) and the anion Chlorite (ClO2-). K+ is a neutral ion, while ClO2- is a weakly basic ion. Therefore, the solution formed by this salt will be basic.

4. C6H5NH3NO2: This salt contains the cation Phenylammonium (C6H5NH3+) and the anion Nitrite (NO2-). Both C6H5NH3+ and NO2- are weakly acidic ions, so the solution formed by this salt will be acidic.

5. CH3NH3Br: This salt contains the cation Methylammonium (CH3NH3+) and the anion Bromide (Br-). Both CH3NH3+ and Br- are weakly acidic ions, so the solution formed by this salt will be acidic.

6. KCl: This salt contains the cation Potassium (K+) and the anion Chloride (Cl-). Both K+ and Cl- are neutral ions, so the solution formed by this salt will be pH-neutral.

7. NaClO: This salt contains the cation Sodium (Na+) and the anion Hypochlorite (ClO-). Na+ is a neutral ion, while ClO- is a weakly basic ion. Therefore, the solution formed by this salt will be basic.

8. NH4ClO: This salt contains the cation Ammonium (NH4+) and the anion Hypochlorite (ClO-). NH4+ is a weakly acidic ion, while ClO- is a weakly basic ion. The acidic nature of NH4+ will dominate, so the solution formed by this salt will be acidic.

9. Fe(ClO4)3: This salt contains the cation Iron (III) (Fe3+) and the anion Perchlorate (ClO4-). Fe3+ does not have any acidic or basic properties, and ClO4- is a weakly acidic ion, so the solution formed by this salt will be acidic.

10. C2H5NH3NO3: This salt contains the cation Ethylammonium (C2H5NH3+) and the anion Nitrate (NO3-). Both C2H5NH3+ and NO3- are weakly acidic ions, so the solution formed by this salt will be acidic.

Based on the analysis above, your classification is correct for all the salts.

Let's go through each salt and its corresponding acidity or basicity:

Al(ClO4)3 - This salt contains the cation Al3+ and the anion ClO4-. The Al3+ ion does not hydrolyze in water, meaning it does not contribute to acidity or basicity. However, the ClO4- ion is the conjugate base of a strong acid (HClO4), making the salt acidic.

LiCl - Both Li+ and Cl- ions come from strong acids and bases, respectively. Therefore, this salt does not undergo hydrolysis and is pH-neutral.

KClO2 - The K+ ion does not hydrolyze in water. However, the ClO2- ion is the conjugate base of a weak acid (HClO2), causing the salt to be basic.

C6H5NH3NO2 - The C6H5NH3+ ion is the conjugate acid of a weak base (C6H5NH2), making the salt acidic.

CH3NH3Br - The CH3NH3+ ion is also the conjugate acid of a weak base (CH3NH2), making the salt acidic.

KCl - As mentioned earlier, both K+ and Cl- ions come from strong acids and bases, respectively. This salt does not undergo hydrolysis and is pH-neutral.

NaClO - The Na+ ion does not hydrolyze, but the ClO- ion is the conjugate base of a weak acid (HClO), resulting in a basic salt.

NH4ClO - The NH4+ ion is the conjugate acid of a weak base (NH3), making the salt acidic. The ClO- ion is the conjugate base of a weak acid (HClO), further contributing to acidity.

Fe(ClO4)3 - The Fe3+ ion does not hydrolyze, but the ClO4- ion is the conjugate base of a strong acid (HClO4), making the salt acidic.

C2H5NH3NO3 - The C2H5NH3+ ion is the conjugate acid of a weak base (C2H5NH2), making the salt acidic.

Your answers appear to be correct.
