Flashcards in Acid And Bases Deck (23):
1

Acid

a substance which forms H+ ions as the only positive ion in aqueous solution.

Properties: Sour, may be corrosive, toxic , harmful, irritant, useful, and can be in food.

2

Bases

an insoluble hydroxide.

3

Alkali

a substance which forms OH- ions as the only negative ion in aqueous solution.

4

Solution

homogeneous mixture composed of two or more substances

5

Corrosive

A highly reactive material of substance that causes obvious damage to living tissue. Acts directly, by chemically destroying the part (oxidation), or indirectly causing inflammation.

6

Toxic

substances which may be harmful to the environment or hazardous to your health if inhaled, ingested or absorbed through the skin.

7

Harmful

a solid, liquid, or gas that through its chemical or physical properties, along or in combination with one or more other chemical substances. cause death, injury or disease in a living thing.

8

Irritant

causes a temporary or reversible inflammation of living tissue (such as eyes, skin, or respiratory organs) by a chemical action when at contact.

9

Indicator

substances whose solutions change color due to changes in pH, as a acid-base indicators.

10

Ph

numeric scale used to specify the acidity or basicity of an aqueous solution.

11

Universal indicator

pH indicator composed of a solution of several compounds that exhibits several smooth colour changes over a pH value range.
indicating the acidity or alkalinity of solutions from 0-14

12

Examples of household acids

Acetic acid- Vinegar
Citric acids- critic fruits
Lasting acid- Milk

13

Examples of household bases

Baking soda
Soap
House hold ammonia

14

acids found in the lab

sulfuric acid
nitric acid
hydrochloric acid
citric acid
acetic acid.

15

Bases found in the lab

sodium hydroxide

16

Weak acid

acid that dissociates incompletely, releasing only some of its hydrogen atoms into the solution. less capable on donating protons. pH of less than 7

17

Weak base

chemical base that does not ionize fully in an aqueous solution.
which protonation is incomplete. pH of greater than 7

18

Concentrated

relatively large quantity of substance present in a unit amount of a mixture. More of solute dissolved in a given solvent.

19

Dilute

the process of reducing the concentration of a solute in solution, usually simply by mixing with more solvent.

20

Reaction of acid and base

React to neutralize the acid and base properties, producing a salt. H(+) cation combined with the OH(-) anion to form water. Compound formed by the cation of the base and the anion of the acid is salt

21

Reaction with acid and metal

A salt, i.e. a combination of two ions, is formed; the particular salt formed depends on the acid used in the reaction is formed.

22

Reaction with acid and carbonate

Salt is produced.

23

Neutral

compound/ substance that is neither acidic nor alkaline
