A weakly acidic solution- Apex
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 weakly acidic solution.
A pH value less than 7.0.
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.

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 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 weakly acidic 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 pH value less than 7.0.
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.
