Concept explainers

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.

I am told that when determining the number of significant figures, if the decimal place is absent, then you start counting from the first nonzero number on the right side and continue counting to the left until you reach the last digit. However, if the decimal place is present, start counting the first nonzero number from the left and continue counting to the right until the final digit has been reached. For example, the number 50 only has two significant figures, while the number 50.00 has four significant figures. However, how does the number 50 have two significant figures? If I have to start countingfrom the right because of the absence of a decimal place, and I have to begin with the first non zero number, I would have to start from 5 and there is nowhere to count further to the left. How does the number 50 have two significant figures?

1) State your interpretation of the meaning of the slope for the first graph you prepared of Volume of Steel Nuts (mL) versus Number of Steel Nuts. Hint: Understanding the meaning of a slope involves several factors: the units which are a ratio of the y axis units over the x axis units, the interpretation of the slope as “number of the y axis units for every one of the x axis units” and the concept that constructing the best line or curve that follows the trend in the data is a sort of averaging of the random error throughout the data.
