Answer:
0.12 M
Explanation:
Molarity of sodium hydroxide = number of moles of sodium hydroxide / volume in liters
equation of reaction between NaOH and Potassium hydrogen phthalate
NaOH(aq) + KHC₈H₄O₄(aq) KNaC₈H₄O₄(aq) + H₂O(aq)
molar mass of KHC₈H₄O₄ = 204.22g/mol
amount required to titrate with NaOH = 0.5816 g
mole of KHC₈H₄O₄ = 0.5816 g / 204.22g/mol = 0.00285 mole
considering the equation, 1 mole of NaOH required 1 mole of KHC₈H₄O₄
0.00285 mole KHC₈H₄O₄ will require 0.00285 mole of NaOH
Molarity = 0.00285 mole / ( 23.73 ml / 1000ml) L = 0.12 M
Answer:
An emulsifying agent is typically characterized by having <u><em>d. one polar end and one nonpolar end.</em></u>
Explanation:
Emulsifiers are substances that have the ability to bind, for example, fats with those substances that have mostly water in their conformation. In other words, the emulsifier facilitates mixtures of two or more immiscible liquid substances.
This is because the molecules of an emulsifier are often lipophilic (attract oil) at one end and hydrophilic (attract water) at the other. In other words it consists of a polar (hydrophilic) head group and a non-polar (hydrophobic) tail.
<u><em>An emulsifying agent is typically characterized by having d. one polar end and one nonpolar end.</em></u>
