Hexanoic acid (structure below to my best ability) is only slightly soluble in water but is readily soluble (with stirring and shaking) in both 0.6 M NaHCO3 and 2.5 M NaOH.

the structure didn't come out right but
sorry i forgot to write im suppose to
give a brief explanation of the reaction for each
i have no idea!!
Have you tried shaking the bottle?
Answered above by DrBob222 AND GK.
The given compound is hexanoic acid, also known as caproic acid, with the formula C6H12O2 and the structure shown.
Hexanoic acid is a carboxylic acid with a long hydrocarbon chain (six carbons). This type of carboxylic acid is generally less soluble in water due to the hydrophobic nature of the hydrocarbon chain. However, it can form hydrogen bonds with water molecules through its carboxyl group, allowing some degree of solubility.
To understand why hexanoic acid is more soluble in NaHCO3 and NaOH solutions, we need to look at the properties of these substances.
NaHCO3 (sodium bicarbonate) is a weak base and can react with acids. When hexanoic acid is mixed with NaHCO3, a reaction occurs where the bicarbonate ion (HCO3-) accepts a proton (H+) from the acid, forming water and the sodium salt of hexanoic acid.
C6H12O2 (hexanoic acid) + NaHCO3 -> C6H11O2Na (sodium hexanoate) + H2O + CO2
This reaction makes hexanoic acid more soluble in the NaHCO3 solution because the sodium salt of hexanoic acid is more polar and has a greater affinity for water than the free acid form.
NaOH (sodium hydroxide) is a strong base and can fully ionize in water, producing hydroxide ions (OH-) that can react with acids. When hexanoic acid is mixed with NaOH, a similar reaction occurs where the hydroxide ion accepts a proton from the acid, forming water and the sodium salt of hexanoic acid.
C6H12O2 (hexanoic acid) + NaOH -> C6H11O2Na (sodium hexanoate) + H2O
Just like in the case of NaHCO3, the formation of the sodium salt of hexanoic acid increases its solubility in the NaOH solution due to the increased polarity of the salt form.
In both cases, stirring and shaking the solution helps to enhance the dissolution by providing mechanical energy to break apart any clumps or aggregates of the compound.
So, in summary, hexanoic acid is only slightly soluble in water but becomes readily soluble in both 0.6 M NaHCO3 and 2.5 M NaOH due to the formation of the more polar and water-soluble sodium salt of hexanoic acid.
