Question

Arrange the following solution; in order of increasing acidity.

Rank solutions from smallest acidity to greatest. To rank items as equivalent, overlap them.
NaCl, NH_4Cl, NaHCO_3, NH_4ClO_2, NaOH
Smallest acidity Largest acidity

Answer 1

To determine the order of increasing acidity, compare the strength of the acids. The order is: NaOH, NaCN, NaCl, NH4NO3, H2SO4.

Step-by-step explanation:

To determine the order of increasing acidity, we need to compare the strength of the acids. Stronger acids have a greater tendency to donate protons (H+) and are therefore more acidic.

The order of increasing acidity for the given solutions is:

1. NaOH
2. NaCN
3. NaCl
4. NH4NO3
5. H2SO4

Step-by-step explanation:

NaOH is a strong base and does not exhibit any acidic properties.

NaCN and NaCl are salts that do not have any acidic properties.

NH4NO3 is a salt, but it can release hydrogen ions and hence has some weak acidic properties.

H2SO4 is a strong acid and has the highest acidity among the given solutions.

Answer 2

To rank the solutions in order of increasing acidity, we consider the strength of the acids formed when they dissolve in water. NaOH is the least acidic, followed by NaCN, NaCl, NH4NO3, and H₂SO4 is the most acidic.

Step-by-step explanation:

To rank the solutions in order of increasing acidity, we need to consider the strength of the acids formed when these compounds dissolve in water. Acidity is determined by the concentration of H+ ions in solution. Higher concentrations of H+ ions indicate stronger acids and thus greater acidity.

1. NaOH: This compound is a strong base and does not produce H+ ions in solution. It is the least acidic.
2. NaCN: This compound is a weak acid and partially dissociates in water to form CN- ions. It is more acidic than NaOH.
3. NaCl: This compound is neutral and does not produce H+ or OH- ions in solution.
4. NH4NO3: This compound is a strong acid and fully dissolves in water to release H+ ions. It is more acidic than NaCN.
5. H₂SO4: This compound is a strong acid and fully dissociates in water to release two H+ ions. It is the most acidic compound in the list.
