Acid/Base Strenght and naming

the following questions Question 1 12 pts Indicate each of the following acids and bases as strong or weak. Also indicate if it is Arrhenius, Bronsted/Lowry (B/L). or Both. 1. LIOH(aq) (Select] Type? [Select] 2. H2SO4 (aq) [Select] Type? [Select] 3. NH3(aq) [Select] Type? [Select] 4. HF (aq) [Select] : Type? [Select) 5. NaHCO3 is what makes up baking soda. If it reacts with vinegar or dissolves in water, it is shown to be a Select] Type? (Select] 6. NH,OH(aq) [Select] Type? [Select)

Answer 1

1.LioH is strong base(metal hydroxide is strong base)

2.H2SO4 is strong acid (easily solouble in water it produce H+)

3.NH3 is weak base.

4.HF is weak acid fluorine is more electronegative does not give H+ so weak acid

5.NaHCO3 is acidic salt

6.NH4OH is weak base(in aqueous solution low OH- ion produce.)

arrhenius acid:an acid is a substance which produce hydrogen ions when dissolved in water.

arrhenius base:an base is substance which produce hydroxyl ion when dissolved in water.

Bronsted -lowry's acid:an acid is species which capable of donating one or more protons to any other substance is called Bronsted-lowry's acid.

Bronsted-lowry's base : A base is species which is capable of accepting one or more protons from acid ,such base is called Bronsted-lowry's Base.

1.LioH is arrhenius Base.

LiOH(aq)------>LI+ +OH-
