The neutralization reaction is defined as the reaction, where an acid solution reacts with a base solution to undergo neutralization, forming a salt. The reaction is said to be completed when the salt is formed.Answer and Explanation:
Leaching of the saprolitic laterite material by sulphuric acid at atmospheric pressure shows that nickel in lizardite is loosely bound within the octahedral layer and as much as 84.8% nickel could be leached under the experimental conditions of 10% (v/v) H2SO4, 90 °C reaction temperature, le...
