Match terms  with  its  description

Acid - a  compound  that increases hydrogen  ion (H+) when  it  is dissolved in a solution

  example  of acid  is   HCl acid  which dissociate   in solution to  give  H+  ion and Cl- ion

Alkaline - a  compound that increases hydroxide  ions (OH-)  when  it is  dissolved  in a solution.

example of alkaline is NaOH  which it  dissociate  in  solution  to  give (OH-) and Na+  ions


PH- value  from 0 to 14  that is used to specify   how acidic or basic a compound is  when it is dissolved in water.

A compound with a  Ph   below  7 is an acid   while a compound  with  a pH  above 7  is alkaline .

PH  of 7  is  for  neutral compounds.

Ion - at atom  or molecule  that has  a positive  or negative  charge.

for example  Na+  ion which is positively charged  and Cl-  ion which is negatively  charged.

Acids increase the hydrogen ion concentration in solution while bases increase the hydroxide ion concentration in solution.

An atom is the smallest particle of  a substance which can take part in a chemical reaction. All substances are composed of atoms of elements. They following is a matching of definitions with the corresponding terms.

  • An atom or molecule that has a positive or negative charge - Ion
  • A compound that increases hydrogen ions (H+) when it is dissolved in a solution - Acid
  • A compound that increases the hydroxide ions (OH−) when it is dissolved in a solution - Alkaline
  • A value from 0 to 14 that is used to specify how acidic or basic a compound is when it is dissolved in water - pH
