Legumes are much easier to grow than other plants, and are more adaptable.

Answer:

Legumes have numerous advantages for health and are also very good for soils.

Explanation:

From a health point of view, according to the Food and Agriculture Organization of the UN, legumes are seeds that contain low sugar, low fat, high fiber, iron and antioxidants, all of which contribute to a better functioning of the human body. But also from an ecological perspective, this plants are great for restoring soils because their are the only group of plants capable of sequestering nitrogen from the atmosphere into the food webs. In food insecure populations usually one of the main problems is the poor state of soils, and also the need for high-nutrient aliments to fight diseases. That is why legumes are such a good source for them.

When neutralizing your acid extracts, you determined how much base solution was needed to fully neutralize your acid and reach a
alukav5142 [94]

Answer:

The amount of base needed is the amount that would give one mole of the hydroxide ion needed to neutralise one mole of the hydroxonium ion from the acid.

Explanation:

The chemical reaction between an acid and a base to form salt and water only is called a Neutralization reaction.  Chemically

H⁺ + OH⁻ = H₂0

Hence, one mole of hydroxonium ion (H⁺) will combine with one mole of hydroxide ion (OH⁻) to give salt and water only.

In a completely neutralized reaction, the resulting salt is formed when there is complete dissociation of the acid and base to give salt and water with a pH of 7.

In the given question, the stated pH of between 8-9 tells us that the salt produced in this particular neutralization reaction is basic or alkaline. This usually occurs when a strong base reacts with a weak acid, producing a higher concentration of the hydroxide ion at equilibrium.

Hence the amount of base needed is the amount that would give one mole of the hydroxide ion needed to neutralise one mole of the hydroxonium ion from the acid.

If the concentration or molarity of the acid is known, then the exact amount of base required to neutralize it can be calculated. This is usually done via titrating the acid against drop wise solution of the base. Neutralization usually occurs when there is a change in colour of the resulting solution. The pH of the resulting solution can be determined using a litmus paper.

A blue litmus paper is indicative of a basic solution while a red litmus paper is indicative of an acidic solution.
