Which of the following is true about acids?
Accepts Protons, creates OH- in water, turns litmus paper blue
Donates Protons, creates H+ in water, turns litmus paper red
Accepts protons, creates OH- in water, turns litmus paper red
Donates protons, creates H+ in water, turns litmus paper blue
The base Ca(OH)2 neutralizes the acid HBr. What salt is created?
CaH2
CaO2
CaBr2
CaH2Br
What is the pH of a chemical that has a hydrogen concentration of 3.9 x 10-4
4.52
8.53
3.41
1.36
What is the pH of a sprite soda that has a hydrogen ion concentration of 5.6 x 10-4?
3.25
2.53
10.75
6.84
Two bases of equal concentration, the weaker base has
Less Hydronium concentration
A greater hydroxide concentration
a higher pH
A lesser hydroxide concentration
HCl has a bond strength of 431.62 and HBr has a bond strength of 366.35. Which acid would be better at conducting electricity? Why?
HCl, because it is harder to dissociate allowing electricity to have more space to pass in water
HBr, it dissociates easier in water creating more ions to pass electricity
Both would have the same conductivity
A base that "dissociates into hydroxide OH- ions in water" is best defined as a:
Arrhenius Base
Bronsted-Lowery Base
Operational Base
Chemical combustion change
A titration is completed between Ca(OH)2 + HNO3 what reaction would the reaction result in?
Ca(OH)2 + 2HNO3 --> CaH + 2NO3OH
Ca(OH)2 + 2HNO3 --> 2H2O2 + CaNO3
Ca(OH)2 + 2HNO3 --> 2H2O + Ca(NO3)2
Ca(OH)2 + 4HNO3 --> CaO + 2H3NO3
