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.

[Tutorial: Empirical formula) This question will walk you through the process of calculating the empirical formula of a 100.0 g sample of an unknown compound from its elemental percent compositions. This problem will be solved via the following sequence of conversions: mass % mass → moles mole ratio → empirical formula. a) Step 1a: When percentages are given, assume that the total mass is 100 grams to determine the mass of each element in grams. (mass % = mass). Then, using the molar masses of each element, convert grams to moles (mass → moles). The unknown compound is 66.6% N by mass. What quantity in moles of nitrogen does a 100.0 gram sample of the unknown compound contain? b) The unknown compound is 28.6% C by mass. What quantity in moles of carbon does a 100.0 gram sample of the unknown compound contain? c) The unknown compound is 4.8% H by mass. What quantity in moles of hydrogen does a 100.0 gram sample of the unknown compound contain

Product Composition and Reaction Stoichiometry Suppose SH2 and O2 react to produce H20, and a sulfur oxide which contains 40.05% sulfur by mass. Complete the reaction equation by entering the coefficients of the reactants and products and also the empirical formula of the sulfur oxide product. SH2 + H20 + All coefficients must be reduced to the smallest possible integers. Note that, while it is not usual to write coefficients of exactly 1, you must enter "1" in the response box, if that is the correct value. The formula for the sulfur oxide must be written with the S symbol first and O second. The usual subscription of numbers in the formula is to be inferred (e.g. the formula for water would be entered simply as "H2O")
and (II) chloride. are formed when aluminum reacts with cobalt If no reaction occurs, type NR in both boxes. Please use symbols, not full names, in your answer. For subscripts, please use full-size numbers. For example, H₂O would be entered as H20. Please don't confuse the letter "o" with the number "zero". Please don't confuse the letter "i" with the letter "1". and The products are Enter the free metal first. Enter the ionic compound second. Please include (aq), (I), (s) or (g) in your answers.
