Types of salts 1

 Hello fam! Welcome to today’s lesson. I am glad to be your host again as we learn chemistry together. Yesterday, we explained the meaning of the term “salt” and I believe that everyone got what we were tying to explain.


Today we would start looking at the types of salts. We would continue with this tomorrow but today we are going to look at three kinds of salts for a start. 


On a lighter note, I believe our lesson yesterday cleared up the erroneous idea that the only kind of salt that exists is the kind of salt that is used to cook in the kitchen. That one is just sodium chloride enriched with other ingredients to improve our health. We commonly refer to it as table salt.


So lets go down to business. What are the types of salts?

1) Normal salts: These are salts that do not contain hydrogen or hydroxide ions in the salt formula. They are usually formed when a neutralization reaction occurs between a strong acid and a strong base such that the reaction is COMPLETE. An incomplete reaction between an acid and a base would produce an acid salt or a basic salt depending on the stoichiometry of the reaction.

E.g NaOH(aq)   + HCl(aq) ---> NaCl(aq) + H2O(l)

      Strong base     Strong acid    Normal salt    Water

2) Acid salt: An acid salt is a salt that contains a replaceable hydrogen in the formula of the salt. 

E.g H2SO4 (aq) +  KOH(aq) ---> KHSO4(aq) + H2O(l)

                                                        Acid salt

Due to the presence of the replaceable hydrogen in KHSO4, the salt would show acidic properties such as reacting with a base, turning blue litmus paper red, etc.

3) Basic salt: A basic salt is a salt that contains a hydroxide moiety in the formula of the salt. E.g

 Mg(OH)2(aq) + HNO3(aq) --> Mg(OH)NO3(aq) + H2O

                                                     Basic salt

A basic salt would still exhibit the properties of a base such as reacting with acids, turning red litmus blue etc due to the presence of the hydroxide moiety in the salt.

Definition of acids 2 - Introduction to Lewis Acids

Image
 Hello fam! Welcome to today’s lesson. We started to look at the concept of acid definition in yesterday’s lesson. We saw yesterday that acids have been defined by Arrhenius and BrØnsted – Lowry. The Arrhenius definition is limited in the sense that it does not account for behavior of acids in nonaqueous media. Did you try the assignment yesterday? The answers are attached to this post. I believe that the concept of proton donation is now clear to you after looking at the images attached. Reach out to me if you have any challenge. Now let us talk about the Lewis definition of acids. This definition of acids was put out by G. N Lewis in 1923. There is a foundation that we need in order to have an understanding of the idea that was put forward by Lewis.  There is something called an orbital in an atom. It is a region in space where there is a high probability of finding the electron. Now let us assume that your office is at No.38 Bronx street. I may not find you everywhere in the compoun

Calculations on pKa and pH

 Hello! I heartily welcome you all to today’s lesson. We are going to look at the last two calculations that pertain to pH, acids and bases today and tomorrow we would commence our discussion on salts to pave way for a discussion on buffers. I hope all the topics so far are making sense? Your feedback would be highly appreciated. Example 8; What is the pH of 0.2 M solution of sodium acetate. The pKa of acetic acid is 1.8 * 10^-5. Solution; We have that the hydrolysis of sodium acetate occurs as follows; CH3CH2COONa(aq) <-> CH3CH2COO^-(aq) + Na^+(aq)    CH3CH2COO^-(aq) + H2O(l) <-> CH3CH2COOH + OH^-(aq) We can see that that the acetate ion acted as a base hence it accepted a proton. We would have to obtain the Kb Kb = 1 * 10^-14/Ka Kb = 1 * 10^-14/1.8 * 10^-5 Kb = 5.6 * 10^-10 Setting up the ICE TABLE, we have that;          CH3CH2COO^-(aq) + H2O(l) <-> CH3CH2COOH + OH^-(aq) I            0.2                                                      0

Bonding in Complex Salts

Image
 Hello! yesterday, we started looking at the complex salt which we called tetramine copper II chloride with the formula; [Cu(NH3)4]Cl2. We did say that this is a complex salt because of the presence to the complex cation [Cu(NH3)4]^2+. I want to state that if we had a complex anion, the salt would also be a complex salt. A typical example of this is; K4 [Fe(CN)6]. The complex ion is  [Fe(CN)6]4- which is anionic and the counter ions in this case are potassium cations. I told you that we will look at the bonding in the complex salt [Cu(NH3)4]Cl2 and why it does not produce simple ions in water. I will try to explain the basics of the concept today as we would still look at coordination chemistry in more detail sometime later.  Now, the complex salt [Cu(NH3)4]Cl2 has both ionic and covalent bonds. The four ammonia molecules are attached to the central copper II ion by a coordinate covalent bond(see the page timeline for an explanation of what a coordinate covalent bond is). We showed the
