Acids
People describe bases as what kind of taste
Bitter
PH stands for power of hydrogen or potential hydrogen
Potential Hydrogen
Is water a neutral or a base
Neutral
What is a common acid?
Hydrochloric Acid
Bases are
Compounds that split apart or dissociate on water and produce a Hydroxide ion
Lemon Juice
What is a neutral solution?
Has a ph level of 7
True or False: There can be gastric acids in our stomachs
True
What happens when Sodium Hydroxide is placed water?
The Na splits apart from the O and H. The OH- is what makes this a base.
A unknown substance is added to a solution and the pH increases. The substance is:
A base
True or False: Neutrals are neither acids or bases
True
What happens when hydrochloric acid is placed with water?
The H and Cl spilt apart. The H+ is what makes this acid
True or False: Substances ate are basic if they have more OH-ions than H+ ions
True
solution with a pH of 11 has a H+ concentration of:
1 × 10-11 moles/liter
Blood is considered neutral
Yes it is
You have a beaker containing 500 mL of a strong base, and you titrate it with 1M HCI
until your pH 7 indicator just turns color, and then stop. The solution:
An acid
A base is also known as a
Alkali
Is a negative pH possible?
Yes it is possible!! The pH scale usually runs from 0 to 14, but if the molarity of hydrogen ions in a strong acid is greater than one you’ll calculate a negative pH value.
True or false : the ph in blood needs to remain constant so that our bodies can function correctly.
True
