Which of the following statements is/are true/false? A. An acid which is completely ionized into ions and produces a large number of H+ ions. For example HCl, H2 SO4, HNO3 B. An acid which is partially ionized in water and produces less number of H+ ions. For example CH3COOH, H2CO3, H2SO2

Which of the following statements is/are true/false? A. An acid which is completely ionized into ions and produces a large number of H+ ions. For example HCl, H2 SO4, HNO3 B. An acid which is partially ionized in water and produces less number of H+ ions. For example CH3COOH, H2CO3, H2SO2 Correct Answer Both A and B are true

The correct answer is option 1 i.e Both A and B are true.

  • Both statements are true.
  • An acid or base's strength refers to its degree of ionization.
  • Strong acids completely dissociate into their ions in water.
  • The strong acids are hydrochloric acid (HCl), sulfuric acid(H2SO4, hydrobromic acid, and nitric acid(HNO3).
  • Weak acids only partially dissociate into their ions in water.
  • Most organic acids are weak acids.
  • The examples of these acids are Acetic acid(CH3COOH), Carbonic acid (H2CO3), Sulfoxylic acid (H2SO2).

Louis Pasteur mixes two acids HCL and HNO3 in the ratio 7 ∶ 5 and filled it in a container. When 9 liters of solution is taken out and the can is filled with HNO3, the ratio of HCL and HNO3 becomes 7 ∶ 9. How many liters of HCL was contained by the container initially?
Which statement is correct about weak acid? Statement 1: An acid that is completely ionized in water and thus produces a very small amount of hydrogen ions is called a weak acid.  Statement 2: Carbonic acid and sulfurous acid are also strong acids.
Which statement is correct about strong acid? Statement 1: An acid that is completely ionized in water and thus produces a very small amount of hydrogen ions is called a strong acid.  Statement 2: Sulphuric acid and nitric acid are also strong acids.
Dr. Xman is diluting concentrated HCl acid by mixing water in it. The quantity of mixture is 32 l. The ratio of concentrated HCl to water is 7 ∶ 1. If 3 l of water is added to the mixture, the ratio of HCl to water changes to new ratio. If he want to change back the new ratio to the original value, how much concentrated HCl is to be added?
In a 5 litre solution of water and HCl, content of HCl is 20%. In order to attain a desirable result, strong HCl is required. Hence, 10 litres of 100% pure HCl is added. What is the strength of HCl in the mixture now?

In a batch process, the reaction takes place in the presence of an acid medium. The acid is drained from the reaction vessel at the rate of 15ml/s as a result of the density difference of the acid from the reacting component. To avoid wastage of acid, it is recycled to an acid tank which has 1000 L capacity. The acid drained from the reaction vessel, picks up 50 g/L solids from the reactor. Acid is fed once again to the process from acid tank. When the process is started, the acid is almost pure in the tank as a result of filtration. As the reaction proceeds, acid in the tank gets more and more contaminated with the solids. The concentration of the solids should not exceed 100 g/L from the process point of view. The batch time is 16h. Estimate whether the concentration of the solids will exceed 100g/L during the batch reaction.
The _________ equation could not be utilized for this part of the titration curve since the H2CO3 ionizes appreciably, thereby reducing the conc. of H2CO3 and changing the ratio of acid to conjugate base significantly.
