Strong Acids
1. Hydrochloric acid – HCl 2. Sulfuric acid – H2SO4 3. Nitric acid – HNO3 4. Hydrobromic acid – HBr 5. Hydroiodic acid – HI 6. Perchloric acid – HClO4 7. Chloric acid – HClO3
Strong Bases
1. Lithiumhydroxide – LiOH 2. Sodiumhydroxide – NaOH 3. Potassiumhydroxide – KOH 4. Rubidiumhydroxide – RbOH 5. Cesiumhydroxide – CsOH 6. Calcium hydroxide – Ca(OH)2 7. Strontium hydroxide – Sr(OH)2 8. Barium hydroxide – Ba(OH)2 As one can see, most of the strong bases are hydroxides of alkali metals or alkaline earth metals.
Strong Acids
Strong acids are characterized by the symbol HA, where H is the hydrogen atom, and A is an electronegative atom or species to which hydrogen is attached. Strong acids are good proton donors and can remain in an aqueous solution. They are classified as highly corrosive substances that can produce dangerous fumes and cause excruciating burns. High concentrations of strong acids should be handled carefully.
Strong Bases
Strong bases are exceptional proton acceptors and electron donors. They can easily deprotonate or remove the proton from other compounds, like weak acids. The proton cannot remain in an aqueous solution for a long time. Aqueous solutions of strong bases are slippery and soapy. Concentrated solutions can produce chemical burns.
Strong Acids
As mentioned before, a strong acid can dissociate completely or 100 percent in water. The disassociation equation is written as follows: HA (aq.) + H2O (l) → H3O+ (aq.) + A–(aq.) Here, water (H2O) as a base reacts with the acid (HA), forming hydronium ion (H3O+) and A–. Thus, A– is the ion that results when the acid loses a proton. A– is said to be the conjugate base of the acid HA. The conjugate base of a strong acid is weak. Examples 1. Hydrochloric acid (HCl) dissociates into hydronium ion...
Strong Bases
Since strong bases dissociate entirely in water, the disassociation equation can be written as follows: BOH (aq.) → B+ (aq.) + OH–(aq.) The metal hydroxide (BOH) dissociates wholly into a metal ion (B+) and hydroxide (OH–). Here, B is an alkali metal or alkaline earth metal. The alkaline earth hydroxides are less soluble in water than alkali hydroxides but are considered strong bases. Examples 1. Sodium hydroxide (NaOH) dissociates into sodium ion (Na+) and hydroxide ion (OH–) ion. NaOH (aq.)...
The acid dissociation constant (Ka) tells how much an acid dissociates in water. Since strong acids dissociate fully into ions, they have large Ka values. Another method of indicating the strength of acids is by taking the negative logarithm of Ka, which gives the pKavalue. pKa = – log [Ka] The lower the pKa, the stronger the acid is. Below is a ta...
The concentration of acids and bases is expressed in terms of pH (“power of hydrogen”) value. The pH value range from 0 to 14 on a mathematical scale. Acidic solutions have a pH close to 0, neutral solutions, such as water, have a pH equal to 7, and basic solutions have a pH close to 14. Strong acids have a pH of around 0-1, and strong bases have a...
Strong Acids
1. Hydrochloric acid is used in refining metals, household cleaning, and maintaining swimming pools. The stomach depends on gastric acid, which is primarily hydrochloric acid. 2. Sulfuric acid is used in car batteries and manufacturing fertilizers. 3. Nitric acid is used in manufacturing fertilizers, making explosives, and extracting gold.
Strong Base
1. Sodium hydroxide, also known as lye or caustic soda, is used to manufacture soap, detergents, and cleaning solutions. 2. Potassium hydroxide, also known as lye or caustic potash, is commonly used to manufacture soaps and cleaning products. It is used in alkaline batteries. 3. Calcium hydroxide, also known as slaked lime, is used to manufacture cement and lime water and clean up spills from strong acids.
The usual list of strong acids are: hydrochloric acid, hydrobromic acid, hydroiodic acid, sulfuric acid, nitric acid, and perchloric acid. A more quantitative way of determining an acid’s strength is through its acid dissociation constant, or Ka.
