By the result of the formation of positive and negative ions, Ionic compounds are formed.

Explanation:

Electrons are actually transferred from one atom to another to form rare gas electron structures for each ion.

Q26. When added to 20 cm of 0.5 M sulphuric acid, which substance would give a neutral solution?

wariber [46]

Answer:

Adding sodium or potassium hydroxide in amounts sufficient to convert all the H2SO4 into Na2SO4 would approximately neutralize the solution. The error would be the result of the imbalance between the basicity of the hydroxide and the acidity of the bisulfate (HSO4) anion. An adjustment in concentration would have to be made to achieve an accurate approximate pH of 7. But then you didn’t ask how much we would need to add.
