ACID-BASE IDENTIFICATION AND CONCENTRATION OF A VINEGAR

TEST 06

Brainstorm

Is a liquid consisting of acetic acid

(CH3COOH), water and other chemicals.

monoprotic

It has a proton to donate, H+

HCl, HNO3

diprotic

Different tipes:

An acid is a molecule or ion capable of

donating a hydron (proton or hydrogen ion

H+), or, alternatively, capable of forming a

covalent bond with an electron pair. An acid

describe solutions with a pH less than

seven.

It has two protons to donate, H+

H2SO4

A neutralization reaction is a

chemical reaction in which an

acid reacts with a base.

CH3COOH + NaOH ---->

CH3COONa + H2O

poliprotic

It has three protons to donate, H+

H3PO4

pH is the negative log of hydrogen

ion concentration in a water-

based solution. The pH scale

measures how acidic or basic a

substance is.

A base describe solutions with a pH

than seven, and there is a range

of how basic can a solution be. Is

the opposite of an acid.
