A weakly acidic solution.
A solution with a ( K_a ) value much less than one is typically a weak acid in equilibrium with its ions. This indicates that the acid does not dissociate significantly in water, resulting in a low concentration of hydrogen ions compared to the undissociated acid. Consequently, the solution has a higher pH and is less acidic. Examples include acetic acid and formic acid, which partially ionize in solution.
A solution with a ( K_a ) value much less than 1 indicates that it is a weak acid, meaning it does not ionize significantly in water. For instance, acetic acid (CH₃COOH) has a ( K_a ) value of approximately 1.8 x 10⁻⁵, reflecting its limited dissociation into ions. This characteristic results in a solution that primarily consists of the undissociated acid, with only a small fraction existing as ions.
A solution with a K value (equilibrium constant) much less than 1 indicates that the reaction favors the reactants over the products at equilibrium. This typically occurs in reactions where the formation of products is not favored due to factors such as high activation energy or unfavorable conditions. An example would be a weak acid dissociating in water, where a small fraction of the acid molecules ionize, resulting in a low K value.
A pOH of 7.0 indicates a neutral solution, not a basic solution. In a basic solution, the pOH would be less than 7.0.
The pH of a solution is a measure of the concentration of hydrogen ions (H+) in the solution. Pure water has a pH of 7, indicating a neutral solution with equal concentrations of H+ and OH- ions. If a solution has a higher concentration of H+ ions than pure water, its pH would be less than 7, making it acidic. The lower the pH value, the higher the acidity of the solution.
A Weakly Acidic Solution
A solution with a very low molarity or concentration would have a low ma value. This could be achieved by diluting a concentrated solution with a large amount of solvent. Alternatively, a weak acid or base solution with a low ionization level would also have a low ma value.
A K value much less than 1 indicates that the reaction strongly favors the reactants at equilibrium. This could suggest a solution where the products are formed at a slower rate compared to the reactants or one in which the reactants are more stable than the products.

1/2 is less than one.
It depends upon whether the inequality is strictly less than (<), or if it is less than or could be equal (≤). For example: if x < 6, x can have any value less than 6, but cannot have the value 6; but if x ≤ 6, x can have any value less than 6, but can also have the value 6. Or put another way, x = 6 is NOT a solution of x < 6, but IS a solution to x ≤ 6.
An unsaturated solution contains less solute than its capacity to dissolve. This type of solution can still dissolve more solute if added, as it has not reached its maximum concentration.
An unsaturated solution is one that contains less solute than the maximum amount it can dissolve at a given temperature. This type of solution has the capacity to dissolve more solute.
An example of an inequality with no solution is ( x < x ). This inequality states that a number ( x ) is less than itself, which is impossible. Since no value of ( x ) can satisfy this condition, the inequality has no solution.
