acids and bases Flashcards
a chemical compound that dissociates into hydrogen ion(s)and and a negatively charged ion when mixed with water
acid
a chemical compounds that has a negative or positive
ion
a hydongen atom that has lost 1 electron, so only the nucleus and its single proton remain
hydongen ion
a linear scale from 0-14 the is a measure of hydrogen ion concentration
PH scale
the ratio of the amount of solute to the volume of solvent
concentration
when a base is mixed with water, it dissocates into a positivly charged ion
hydroxide ion
a chemical compund that dissocates into hydroxide ion(s) and a positively charged ion when mixed with water
base
when a chemical compound is disolved in a solvent and it seperates into 2 or more ions
dissocate
the substance that is disolved when a solution is prepared
solute
the substance that something is disolved into when a soultion is prepared or is present in the largest amount
solvent
a mixture when one substance is mixed into another
solution
when a less concentrated soultion is prepared by adding additonal solvent
dilution
when an acid and base react to form a water molecule and reduce the hydrogen ion concentration
Neutralization
the lower the ph is the more
acidic
the higher the ph is the more
basic
the higher the ph the more _____ ions
Hydroxide
the lower the ph the more _____ ions
Hydrogen
what makes acids and bases chemically react
H+ and OH- ions
when a solution is diluted by a factor of 10 and over
serial dilution
what can you do to change the ph of an acid
add a stronger acid, add water, add a base
