Working with Solutions :

Question 1

How do we convert dcm^3 into cm^3?

Answer 1

= multiply by 1000

Question 2

How do we calculate the concentration of a solution ?

Answer 2

= concentration(mol/dm^3) =
= amount of substance (mol)
/
= volume (dm^3)

Question 3

What are monoprotic acids?

Answer 3

contain one h+ ions per unit
reacts with sodium hydroxide in the ratio 1:1

Question 4

What are diprotic acids ?

Answer 4

= two H+ ions per unit
= react with sodium hydroxide at the ratio 1:2

Question 5

What are trioprotic acids?

Answer 5

= 3 H+ ions per unit
= react with sodium hydroxide in the ration 1:3
