1. What will happen if we accidentally add water to acid? Explain why? 2. Why is it important to understand the methods of expressing concentration of solutions?
If you add water to acid, you form an extremely concentrated solution of acid initially and the solution may boil very violently, splashing concentrated acid.The concentration of a solute is very important in studying chemical reactions because it determines...

what is meant by basicity and acidity of the compound .
how to find the basicity and acidity of the compounds?
Acidity is the ability of compound to lose hydrogen ion H+, leaving an anion behind. Acidity depends on the stability of the anion formed. The most acidic organic compound are...

why the size of anion greater then anion explain with example
When an atom gains an electron, it becomes a negatively charged ion that we call an anion. Anions are larger in size than their parent atoms because they have one...

Arrange the following in order of decreasing basic strength, justify your answer: alkanide anion , alkenide anion, alkynide anion.
The anions can be arranged in order of decreasing basic strength as follows: Alkynide > alkenide > alkanide The basic strength is defined by the capability of anion to use...

How do the pKa, basicity and nucleophilicity vary in the following moieties? Explain taking into consideration their conjugate acids. Cl- , CN- , RS- , R3N, R2NH, OH-
Basicity is a subset of nucleophilicity. All nucleophiles are Lewis bases; they donate a lone pair of electrons. A “base” (or, “Bronsted base”) is just the name we give to...

What is difference between basicity and nucleophilicty? Discuss the structural
features which affect the basicity of a molecule.
Answer: Basicity is a thermodynamic property and Nucleophilicity is kinetic property. Basicity is the measure in which extent base can abstract the proton. If Basicity is high equilibrium will favour...

Explain how you would use the Arrhenius concept to explain the basicity of Na2CO3 and acidity of AlCl3.
Even though both compounds do not contain H+ and OH- ions, Arrhenius concept in these cases can be applied from the point that adding Na2CO3 to water increases the concentration...

Discuss the basicity of pyridine
The nitrogen center of pyridine features a basic lone pair of electrons. This lone pair does not overlap with the aromatic π-system ring, consequently pyridine is basic, having chemical properties...

1. How does electronegativity influence acidity and basicity of a substance.
2. Explain the behavior of ions in solution.
The higher the electronegativity, the more pronounced are the acid properties. Accordingly, the main properties below.When interacting with water, ionic substances decompose into ions - cations and anions. At the...
