Walls of stomach secrets acids to make the stomach acidic and for the digestion of food, when the acid is secreted in excess it leads to indigestion, heart burn, (or) gastric ulcers. The chemicals which are used to neutralize the excess acid present in the gastric juice and to raise the pH of stomach upto an appropriate level are called antacids.
Antacids does not contains

A

NaOH

B

`Mg(OH)_2`

C

`Al(OH)_3`

D

`NaHCO_3`

Text Solution

Verified by Experts

The correct Answer is:
A
NaOH is not an antacid

Walls of stomach secrets acids to make the stomach acidic and for the digestion of food, when the acid is secreted in excess it leads to indigestion, heart burn, (or) gastric ulcers. The chemicals which are used to neutralize the excess acid present in the gastric juice and to raise the pH of stomach upto an appropriate level are called antacids. The acid secreted in stomach?

Walls of stomach secrets acids to make the stomach acidic and for the digestion of food, when the acid is secreted in excess it leads to indigestion, heart burn, (or) gastric ulcers. The chemicals which are used to neutralize the excess acid present in the gastric juice and to raise the pH of stomach upto an appropriate level are called antacids. Which acts as natural antacid ?

(A): A mixture of Mg (OH)_(2) is better antacid than NaHCO_(3) . (R): NaHCO_(3) makes stomach alkaline and triggers the over production of acid where-as a mixture of Al(OH)_(3) and Mg(OH)_(2) does not increase the pH above 7 in stomach.

All titration which involves the direct titration of Iodine with a reducing agent are grouped under lodimetry. Iodimetry is employed to determine the strength of reducing agent such as sodium thio sulphate I_(2) + 2Na_(2)S_(2)O_(3) rarr 2I^(-)+S_(4)O_(6)^(-) If iodine is liberated as a result of chemical reaction involving oxidation of an idodide ion by a strong oxidizing agent in neutral or acidic medium the liberated iodine is then titrated with reducing agent. This titration is called lodometry. Todometry is used to estimate the strength of oxidizing agent. For example the estimation of Cu^(++) with thiosulphate. Cu^(+ +) +I^(-) Cu_(2)I_(2)+I_(2) , I_(2) +S_(2)O_(3)^(-) rarrS_(4)O_(6)^(-) +I^(-) Starch used as indicator near the end point which form blue colour complex with I_(3)^(-) . The blue colour disappears when When 159.50g of CuSO_4 in a solution is reacted with KI, then the liberated iodine required 100 ml 1 M Na_(2)S_(2)O_3 for complete reaction, then what is the percentage purity of sample used in making the solution.
