Answer 1

Answer on Question #44512 – Chemistry - Inorganic Chemistry

Question:

the volume of 0.1M of sulfuric acid required to neutralize completely 40ml of 0.2 M of sodium hydroxide is what?

Solution:

$$H _ {2} S O _ {4} + 2 N a O H = N a _ {2} S O _ {4} + 2 H _ {2} O$$

Amount of substance of sodium hydroxide is:

$$N (NaOH) (mmole) = 40 * 0.2 = 8$$

The required volume of 0.1M of sulfuric acid is:

$$V (H_2SO_4) (ml) = 8 / 0.1 * 2 = 40$$

Answer: 40ml
