Chapter 6.3, Problem 3MI

Summary Introduction

To fill:

The correct term in the given definitions.

Introduction:

Water is wonder liquid, made up of one oxygen atom and two hydrogen atoms. It is a polar molecule. Its bent shape results in a slightly positive charge on the hydrogen atoms and a slightly negative charge on the oxygen. As a result it forms hydrogen bonds. It is the universal solvent because many substances dissolve in it.

Answer to Problem 3MI

S.no	Term
1	Base
2	Acid
3	Solvent
4	Buffer
5	pH
6	Solute

8	Polar molecule
9	Solution
10	Mixture

Explanation of Solution

Base is any substance in an aqueous medium that releases hydroxide ions.

Acid is any substance in an aqueous medium that releases hydrogen ions.

The solvent is a liquid substance in which another substance is dissolved to form solution.

A buffer solution is a solution which is resistant to changes in pH when small amounts of an acid or base are added to it.

pH is a quantitative measure of the acidity or basicity of aqueous or other liquid solutions,

Solute is a substance that is being dissolved by a solvent in some solution.

The hydrogen bond is a strong intermolecular force created when a hydrogen atom bonded to an electronegative atom.

Polar molecule is a molecule with the oppositely charged regions.

Solution is a homogeneous mixture in which ingredients are evenly distributed throughout the mixture.

A mixture is a combination of different substances, in which every substance preserve its fundamental characteristics.
