Answer:
Acid neutralizes base to form salt and water while white colour neutralizes black colour to form grey colour.
Explanation:
Neutralization is simply the process whereby an acid and a base are mixed to produce salt and water. Now, this reaction also involves the mixing of the hydrogen ions of the acid and hydroxide ions of the base to form the salt and water. It is similar to mixing 2 paints to form another colour in that in the neutralization reaction 2 compounds are mixed to neutralize each other to form another compound while in mixing black and white to form grey the two colors are mixed together and thereby neutralized to form another colour which is grey.
Physicalchange. Lighting a match and letting is burn is an example of a chemical change. Chemical reactions cause chemicalchanges. In a chemical reactiontwo or more substances, called the reactants, form different substances called products.
The answer is (3) moles of solute per liter of solution. That is what the definition of molarity of a solution means. The equation is concentration = mol number of solute/ volume of solution.
