🗑
|
||||
| weak base | a base that releases few hydrogen ions in a solution (ionizes slightly)
🗑
|

🗑
|
||||
| indicator | a compound that can reversibly change colors depending on pH of the solution.
🗑
|

| neutralization reaction | when acids and bases come together to form water
🗑
|
||||
| equivalence point | the point when two solutions used in a titration are present in equal amounts
🗑
|
||||
| titration | a method used to determine the concentration of a substance by adding a solution of known volume
🗑
|
||||
| buffer solution | a solution with resists change in pH/ changes pH very slightly/ keeps pH constant when small amounts of acid or base are added
🗑
|
||||
| end point | occurs in a titration when the indicator changes color
🗑
