Chapter 4 - Types of Chemical Reactions and Solution Stoichiometry

Volumetric analysis

________: A technique for determining the amount of a certain substance by doing a titration.

hydroxide ion

The ________ is such a strong base that for purposes of stoichiometric calculations it can be assumed to react completely with any weak acid that will be encountered.

Photosynthesis

________ is a very important oxidation- reduction reaction.

Nature of Aqueous Solutions

Like dissolves like "is a useful rule for predicting solubility 4.2 The ________: Strong and Weak Electrolytes.

Sodium chloride

________ produces ions in aqueous solutions that are strong electrolytes.

Titration

________: Involves delivery of a measured volume of a solution of known concentration into a solution containing the substance being analyzed.

strong electrolyte

A(n) ________ is a substance that completely breaks apart into ions when dissolved in water.

Molarity

________: The amount of solute per volume of solution in liters.

Ethanol

________ is very soluble in water.

Non-electrolytes

________ are substances that dissolve in water but do not produce any ions.

Chemists

________ usually write the net ionic equation for a reaction in solution because it gives the actual forms of the reactants and products and includes only the species that undergo a change.

nuclear power

Water helps moderate the earths temperature: it cools automobile engines, ________ plants, and many industrial processes.

Oxidation states

________ are written +n or- n, the number is written after the plus or minus sign.

Dilution

________ with water does not alter the numbers of moles of solute present.

covalent bond

For a(n) ________ between two identical atoms, the electrons are split equally between the two.

formula equation

The ________ gives the overall reaction stoichiometry but not necessarily the actual forms of the reactants and products in the solution.

Net ionic equations

________ include only those components that undergo changes in the reaction.

precipitation reaction

A(n) ________ also can be called a double displacement reaction.

Oxidation Reduction Reactions

When a strong electrolyte is resent, write it as separated ions 4.9 ________.

Reduction

________: A decrease in oxidation state.

Redox reactions

________: One or more electrons are transferred.

solid containing ions

When a(n) ________ dissolve in water, the ions separate and move around independently.

strong electrolytes

In a complete ionic equation, all substances that are ________ are represented as ions.

Sodium chloride

________ can be formed by the reaction of elemental sodium and chlorine.

oxidation states

For an ion, the sum of the ________ must equal the charge of the ion.

Dilution

________ produce typically involves two types of glassware: a pipet and a volumetric flask.

strong electrolytes

The complete ionic equation represents as ions all reactants and products that are ________.
