11.4 A closer look at neutralization

Question 1

what is the ionic equation

Answer 1

it shows just the ion that take part in the reaction

Question 2

example of an ionic reaction

Answer 2

HCl + NaOH –> NaCl + H2O
H+ Cl- + Na+(OH)- —> NaCl- + H2O
H+ + (OH)- = H2O

Question 3

What’s happening during neutralization

Answer 3

H+ ions combines with OH- ions to form water molecules

Question 4

is magnesium oxide soluble

Answer 4

magnesium oxide is insoluble

Question 5

how does magnesium oxide neutralize an acid

Answer 5

magnesium oxide is a lattice which is insoluble when it mix with HCl it forms magnesium chloride which is soluble.

Question 6

equation for magnesium oxide with HCl

Answer 6

HCl + MgO —> MgCl2 + H20

Question 7

acids are?

Answer 7

proton doners

Question 8

bases are?

Answer 8

proton acceptors

Question 9

what acid is in the stomach

Answer 9

HCl

Question 10

indigestion is due to excess hydrochloric acid. How do you neutralize it?

Answer 10

like of magnesia contains magnesium hydroxide, which will neutralize it.

Question 11

what are spectator ions

Answer 11

The ions which do not participate in chemical reactions and present the same on both sides of the reactions
