Chemistry has been a troubling topic for students. It has different branches, making it hard for learners to master each concept on their own. But, it is not impossible to self-learn chemistry. There needs to be a desire in minds of pupils to understand their discipline, merely memorization or blindly using rote memory will not help.
When provided with difficult topics students feel distressed. Using their intellect and resources such as internet and library books any issue can be handled. An example of questions that puzzle students include enter the net ionic equation, including phases, for the reaction of agno3(aq) with k2so4(aq). To deal with such topics students have to first know problems of chemistry and then discover what helps them in assignments.
Branches of chemistry
As a student is introduced to the discipline, the basics of the periodic table, different elements, compounds, protons, electrons and neutrons are introduced to them. As they progress, each child is introduced to newer topics of balancing equations, organic chemistry and others.
Each branch has its unique properties and even though at its core the concepts are same. In each different strand of this discipline there are unique properties to be noted. In the entirety of chemistry one common problem which is faced by students is learning different kinds of equations and applying them to other disciplines.
Problems of equations â€“ the Ionic Type
Equations in chemistry can be of various types but ionic equations are most difficult among them. An ionic equation is where an aqueous solution composed of electrolytes is denoted in dissociated manner. When elements such as salts dissolve in a liquid then the chemical equation is ionic in nature.
There are different phases which are involved in the solving of such equations. Begin by balancing the molecular equation completely. This should be followed by breaking down soluble electrolytes which have the sign (aq) next to them into ions. The charge of each ion should be shown along with correct formulas. All other compounds need not be broken down into ions.
A classic example to understand these kind of equations are to enter the net ionic equation, including phases, for the reaction of agno3(aq) with k2so4(aq). There are two phases in which this equation can be solved. First is by simple balancing, secondly complete breakdown is shown. Â It should be noted that ionic compound reactions in aqueous solutions differ from other reactions in steps and end results.
The simple way to tackle such equations is by first understanding how the process works and then constantly practicing them. Chemistry can pose other problems its various other branches and pupils need to be ready to face and overcome such issues.
Tips to cope
Without a doubt students will need help in chemistry, but it does not mean that they need any special tools. The following tips can help greatly:
These simple tips can assist any learner to ace their assignments.
