Molecules made up of two or more elements are called compounds. Water, calcium oxide, and glucose are molecules that compound.
Explanation:
Chemical formula of hexanoic acid is . According to Bronsted-Lowry, acid upon dissociation gives conjugate base and base upon dissociation gives conjugate acid.
Hexanoic acid will dissociates as follows.
Therefore, we can conclude that conjugate acid of hexanoic acid is
Answer:
part b:
Sodium bicarbonate is a white, crystalline powder that sometimes forms lumps. It is odorless and has a bitter, salty taste. At room temperature, it is a solid. Solubility, or the ability of a substance to dissolve in water, is also a physical property. Sodium bicarbonate is soluble in water and can be separated from water through evaporation.
Explanation:
According to the Arrhenius concept, the strength of an acid depends upon the H⁺ ions furnished by the acid.
<h3>What is the Arrhenius theory of acids?</h3>
According to the Arrhenius theory, acids are those substance which will give H⁺ ion in an aqueous solution.
And acidity of any substance will be calculated by using the pH value which can be calculated as pH = -log[H⁺].
- Hydrolysis will not able to define the strength of the acid.
- Concentration of the acid is also not valid to define the strength of the acid because all acids will not have H⁺ ion.
- Number of moles of the base which are used for neutralization is also not used to define the strength of Arrhenius acid.
Hence H⁺ ions furnished by the acid is used to define the strength of Arrhenius acid.
