chemistry introduction to acid and base neutralisations in everyday life acids and bases in daily life neutralisation reaction

  1. Vanillic acid

  2. Lactic acid

  3. Oxalic acid

  4. Acetic acid

Show answer
Correct Option: D
Explanation:

Vinegar is a liquid consisting about 5-20% of organic acid that is acetic acid $(CH _3COOH)$ and water. It is a mild acid. Vinegar is mainly used as cooking ingredient.

Which of the following base is used as antacid to neutralize stomach acidity?

chemistry introduction to acid and base neutralisations in everyday life acids and bases in daily life neutralisation reaction

  1. ${ Mg(OH) } _{ 2 }$

  2. $KOH$

  3. ${ Ca(OH) } _{ 2 }$

  4. $NaOH$

Show answer
Correct Option: A
Explanation:

Magnesium hydroxide is also known as milk of magnesia and it is a common component of antacids and laxatives. It interferes with the absorption of folic acid and iron. It carries away much of the body's supply of potassium and neutralizes the stomach acid.

To protect tooth decay we are advised to brush our teeth regularly. The nature of the toothpaste commonly used is:

chemistry introduction to acid and base neutralisations in everyday life acids and bases in daily life neutralisation reaction

  1. acidic

  2. basic

  3. netural

  4. corrosive

Show answer
Correct Option: B
Explanation:

Mouth has salivary amylase enzyme and the process of digestion starts from mouth making the acidic environment which causes the tooth decay so it is neutralized by using toothpaste basic in nature.

Milk of magnesia is an:

chemistry introduction to acid and base neutralisations in everyday life acids and bases in daily life neutralisation reaction

  1. acid

  2. antacid

  3. alkali

  4. rock salt

Show answer
Correct Option: B,C
Explanation:

Milk of magnesia is $Mg(OH) _2$, it is an alkali.

Antacid is those compounds which completely neutralizes an acid.
For example: $\underbrace{Mg(OH) _2} _{Base}+\underbrace{H _2SO _4} _{Acid}\longrightarrow  \underbrace{MgSO _4} _{Neutral\ salt}+H _2O$
Thus, milk of magnesia is also an antacid.

Aluminum hydroxide is used for :

chemistry introduction to acid and base neutralisations in everyday life acids and bases in daily life neutralisation reaction

  1. fire extinguishers

  2. antacid

  3. water purification

  4. all of the above

Show answer
Correct Option: D
Explanation:

Aluminum hydroxide is an interesting base, because it has a wide number of applications, including its use in antacids. As such, it reacts with and neutralizes stomach acid, and for that reason is found in commercial antacids. It is useful in fire extinguishers as a foaming agent. Aluminum hydroxide is also used in water purification, in dyeing garments, and in the production of certain kinds of glass.

Which base is employed as the electrolyte in alkaline batteries?

chemistry introduction to acid and base neutralisations in everyday life acids and bases in daily life neutralisation reaction

  1. $Ca(OH) _2$

  2. $Al(OH) _3$

  3. $FeOH$

  4. $KOH$

Show answer
Correct Option: D
Explanation:

Aqueous potassium hydroxide is employed as the electrolyte in alkaline batteries based on nickel-cadmium, nickel-hydrogen, and manganese dioxide-zinc. Potassium hydroxide is preferred over sodium hydroxide because its solutions are more conductive.
