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.
pleeeeeeease solve question 1
![Q1: The indicator used and the color change in the bleach analysis experiment:
C) I 2 \red to colorless
A) starch\ deep blue to colorless
B) I2 \red to yellow
D) starch\ deep red to colorless
02: To calculate the molecular weight of a volatile liquid, the liquid was vaporized in an Erlenmeyer flask
which had a total volume of 152 mL. In the procedure, the flask containing an excess amount of the
volatile liquid was covered with aluminum foil with a tiny pinhole, and then the flask and the liquid was
laced in a boiling water bath at 100 °C. The atmospheric pressure was measured 754 torr with a barometer
the room. As the liquid in the flask vaporized, the excess vapor escaped through the pinhole until no
visible liquid remained in the flask. The flask was then removed from the water bath and allowed to cool.
The mass of the flask, foil, and vapor was 94.53 g. The initial mass of the dry, empty flask and foil was
94.12 g.
From this information, calculate the molecular weight of the volatile liquid in grams per mole.
A) 48
