Explanation:
Hello,
In this case, given the 0.0990 moles of the salt are soluble in 1.00 L of water only, we can infer that the molar solubility is 0.099 M. Next, since the dissociation of the salt is:
The concentrations of the A and B ions in the solution are:
Then, as the solubility product is defined as:
Due to the given dissociation, it turns out:
Regards.
Answer: Hence, 2 moles of NaOH would neutralize 1 mole of
Explanation:
One mole of hydrochloric acid neutralizes one mole of sodium hydroxide to give one mole of sodium chloride and one mole of water
When sulfuric acid is used in the place of HCl , 1 mole of sulfuric acid will neutralizes the 2 mole of sodium hydroxide and gives one mole of sodium sulfate and 2 moles of water. As we can see from the reaction:
Hence, 2 moles of NaOH would neutralize 1 mole of
