What does the baking soda react with when making pancakes?
Lactic acid in milk
What is the name of the scale used to measure the acidity or basicity of a solution?
pH scale
What do acids taste like?
sour
Cranberry juice breaks down it releases more H+ ions than OH- ions. What kind of solution would that be considered?
Acid
Why do bubbles form when making pancakes?
Sodium bicarbonate combines with the milk, creating carbon dioxide gas.
What pH is neutral?
7
What do bases taste like?
soapy
Glucose has a pH of 7. What does that tell you about the number of H+ and OH- ions it has?
they are equal
What is the difference between baking soda and baking powder?
Baking soda: sodium bicarbonate only, needs an acid to react
Baking powder: sodium bicarbonate and solid acids, only needs a liquid to help them react
What kind of solution has an excess of H+ ions?
acidic
Is baking soda an acid or base?
base
What range of pH do acids have?
lower than 7
If you used water instead of milk to make pancakes, how would that change the outcome (besides flavor)?
It would not be as fluffy since not as much CO2 would be produced.
What kind of solution has an excess of OH- ions?
basic
If red litmus paper turns blue, what kind of solution do you have?
basic
What range oh pH do bases have?
greater than 7
What makes 'self rising' flour self rising?
It contains baking powder (solid acids & sodium bicarbonate)
What is the range of the pH scale?
