Acids
What acids produce in water.
What are hydrogen ions?
What is hydroxide (OH-) ions?
What the symbol "pH" stands for.
What is potential hydrogen?
The color litmus paper turns in the presence of an acid
red
The difference between a base and its conjugate acid or an acid and its conjugate base?
What is one hydrogen ion?
Resist pH changes when small amounts of acids or bases are added; extremely important for the blood in the body to keep our pH balanced.
What is a buffer?
What are at least three properties of a base?
Any combination of: taste bitter, feels slippery, turns litmus paper blue, pH greater than 7, accepts H+ ions or produces OH- ions in water, does not react with metal, and are electrolytes.
The solution that is always neutral.
What is water?
the reaction when a base and a acid are combined
neutralization
The base in the following equation:
HPO4-2 + H2O --> H2PO4- + OH-
What is HPO4-2?
A list of at least 3 properties of acids.
Any combination of these works: turns litmus paper red, taste sour, electrolyte, highly reactive with metal, creates H+ ions in water, and pH less than 7.
What is the Symbol for hydroxide ion?
OH-
Which level of acids can't dissociate completely or can't form ions easily? pH usually between 4, 5, or 6?
Weak acid/base
This scale measures the concentration of H+ ions in a solution.
These types of compounds can be either an acid or a base.
What is amphoteric?
What is the symbol for a hydrogen hydrogen ion as found in acids placed in water?
H+
According to Bronsted-Lowry, how can something be classified as a base?
something that is capable of accepting a hydrogen ion/proton
The pH scale goes up and down by a factor of ____.
What is 10?
The neutral pH number.
What is 7?
The conjugate acid in the following equation:
HBr + CH3NH2 --> Br- + CH3NH3+
What is CH3NH3+?
According to the Bronsted-Lowry definition, what makes a solution an acid?
it is capable of DONATING H+ ions
The neutralization skeleton formula.
What is acid + base --> water + salt?
When combined together, only a ________ ________ would be able to neutralize a strong acid.
What is a strong base?
An organic compound that changes color in the presence of acids and bases, such as litmus paper, red cabbage extract, phenolphthalein, or bromothymol blue?
What is an indicator?
An acid has a conjugate base because after it donates an H+ ion during the reaction, it would technically be able to ______ an H+ ion, making it behave like a Bronsted-Lowry base.
What is receive or accept?
