acids and bases

Question 1

Acids

Answer 1

tart or sour taste
cause indicators to change colors
react with bases to produce salt and H2O
produced hydrogen ions when dissolved in H2O

Question 2

bases

Answer 2

bitter taste and feels slippery
react with acids to form salt + water
produce hydroxide ions when dissolved in H2O (alkalis)
all alkalis are bases, but not all bases are alkalis

Question 3

naturalization reactions

Answer 3

used to determine the exact concentration of an acid or a base
The equivalence point is where neutralization reaction exactly neutralize each other
the end point is where the indicator changes color
these reactions are always exothermic

Question 4

indicators

Answer 4

acids and bases can be distinguished using this.
weak acids or bases who’s conjugates have different colors.
the color change can be used to determine pH

Question 5

Arrhenius Acids

Answer 5

a chemical compound that increases the concentration of hydrogen ions, H+ in aqueous solution

Question 6

Arrhenius Bases

Answer 6

a substance that increases the concentration of hydroxide ions, OH- in aqueous solution

Question 7

Bronsted-Lowery

Answer 7

Acids: donates protons
Base: accepts protons

Question 8

amphoteric substance

Answer 8

substance that acts as an acid or a base
