Ima Kemist is analyzing a solution of kansui (potassium carbonate) by precipitating the carbonate with Epsom salt (magnesium sulfate). a. Write the balanced molecular and net ionic equations for the reaction between aqueous potassium carbonate and aqueous magnesium sulfate. Include states of matter. b. Ima weighs a coffee filter and filters out the precipitate formed from her experiment. She allows the filter and precipitate to dry, then weighs the filter and precipitate, calculating the mass of precipitate by difference. However, the filter and precipitate were not completely dry. Is the mass Ima calculated higher than, lower than, or equal to the true mass of the precipitate? c. Ima uses the mass of the wet precipitate to calculate the concentration of potassium carbonate. Is this calculated concentration higher than, lower than, or equal to the true concentration of the sample?
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.
Ima Kemist is analyzing a solution of kansui (potassium carbonate) by precipitating the
carbonate with Epsom salt (magnesium sulfate).
a. Write the balanced molecular and net ionic equations for the reaction between aqueous
potassium carbonate and aqueous magnesium sulfate. Include states of matter.
b. Ima weighs a coffee filter and filters out the precipitate formed from her experiment.
She allows the filter and precipitate to dry, then weighs the filter and precipitate,
calculating the mass of precipitate by difference. However, the filter and precipitate
were not completely dry. Is the mass Ima calculated higher than, lower than, or equal to
the true mass of the precipitate?
c. Ima uses the mass of the wet precipitate to calculate the concentration of potassium
carbonate. Is this calculated concentration higher than, lower than, or equal to the true
concentration of the sample?
