1) A drop of phenolphthalein is added to a solution of 1.0 M H2SO4 with a volume of 10.0 mL. The solution is mixed with 8.2 mL of 0.70 M NaOH. After the reaction is complete, is the solution acidic, basic, or neutral? What color is the indicator? Show all calculations and explain the answer with numbers.
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
1) A drop of phenolphthalein is added to a solution of 1.0 M H2SO4 with a
volume of 10.0 mL. The solution is mixed with 8.2 mL of 0.70 M NaOH.
After the reaction is complete, is the solution acidic, basic, or neutral? What
color is the indicator? Show all calculations and explain the answer with
numbers.
2)) A 50.0 mL sample of H2SO4 is neutralized with a KOH solution having a
concentration of 0.400 M. If 22.6 mL of KOH are required to complete the
neutralization, what is the concentration of the sulfuric acid solution?
