Calculate the pH of a 2.0 M H2SO4 solution.
noname [10]
 <span>H2SO4 gives 2 moles oh H+ per mole of acid 

[H2SO4] = 2M so [H+] = 4M 

pH = -log(4) = -.6 

Therefore, the pH </span><span>of a 2.0 M H2SO4 solution is -0.6

Which of the following is acidic when dissolved in water? a. SO b. NO2 c. Na, d. Cao e. Two of these modern periodic table are a
Zielflug [23.3K]

Answer: e. Two of these

Explanation:

(a) SO_2

When SO_2 is dissolved in water. It reacts to form sulfurous acid.  The chemical reaction is shown below:

SO_2+H_2O\rightarrow H2SO_3

Therefore,  SO_2 is acidic when dissolved in water.

(b) NO_2

When NO_2 is dissolved in water. It reacts to form nitric acid.  The chemical reaction is shown below:

3NO_2+H_2O\rightarrow 2HNO_3+NO

Therefore, NO_2  is acidic when dissolved in water.

(c) Na

Sodium is a metal. It gives sodium hydroxide on reaction with water. The chemical reaction is as follows:

&#10;Na+H_2O\rightarrow NaOH&#10;+H_2

Therefore, Na is basic when dissolved in water.

(d) CaO&#10;

Calcium oxide is a metallic salt. It gives calcium hydroxide on reaction with water. The chemical reaction is as follows:

CaO+H_2O\rightarrow Ca(OH)_2,

Therefore,  CaO&#10; is basic when dissolved in water.

(e)  Two of these.

Since both SO_2 and  NO_2  give acids when dissolved in water, both are acidic.
