Write observation and complete molecular equation. Identify the precipitant using solubility chart. B1: Phenolphthalein is pink in presence of NaOH. It will become colorless as HCl is added. Some heat can be felt. Observation: Equation: B2: Gas bubbles will evolve from the test tube when solid Na2CO3 is added to HCl. Observation: Equation:
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.

PART I - METATHETICAL REACTIONS
Metathetical reactions are sometimes called double-replacement reactions. In these reactions two compounds exchange ions with each
other. Metathetical reactions are usually carried out in aqueous
solution. The general formula for this type of reaction is
AC+BD→AD+BC
A.
PRECIPITATION REACTIONS
In this type of metathetical reaction, a precipitate is formed. The precipitate is indicated by an arrow pointing down or the
physical state indicator (s). The formation of a precipitate may be predicted by using solubility rules or a solubility chart.
Examples:
AgNO,(aq) + NaCl(aq) → AgCl(s) \ + NaN0;(aq)
In these reactions, all of the soluble compounds are considered dissociated into their ions. The ions, which are not involved in the
precipitate, are considered "spectator ions".
PROCEDURES: Perform each
Cd( NO; ), (aq) + (NH,),S(aq) → 2 NH, NO;(aq) + CdS(s)+
of the following reactions.
Write your observations in your
notebook and write the equation for each reaction. Indicate the precipitate.
1.
To a dropperful of 0.1 M calcium nitrate in a test tube, add a dropperful of 0.1 M sodium carbonate.
2.
To a dropperful of 0.1 M magnesium sulfate in a test tube, add a dropperful of 0.1 M sodium hydroxide.
3.
To a dropperful of 0.1 M sodium nitrate in a test tube, add a dropperful of 0.1 M potassium chloride.
