Physical Science Ch 23

Endpoint

the point where the indicator changes color and stays that way in a titration

pH of the solution

best indicator of the number of hydronium ions in a solution

Neutral

double arrows poniting in opposite directions indicate an acid in an equation

Salt

compound formed in solution from the negative ion of an acid and the positive ion of a base

Buffers

blood contains this which allow small amounts of acids or bases to be absorbed without harmful effects

Standard Solution

solution for which the concentration is known in a titration

Indicators

organic substances that change color in the presence of an acid or a base

Hydronium Ions

H3O+

Ester

when the substances acetic acid and ethyl alcohol react they form this

Acid

substance that produces H+ ions ina solution

Base

substance that produces OH- ions in a solution

Soaps & Detergents

characteristic of these two include long carbon chains, used for cleaning, classified as an organic salt

Neutralization

reaction between an acid and a base that produces a salt and water

Neutralize

antacids work because they do this to excess stomach acid

Basic

type of solution that contains more OH- ions than H3O+ ions

Base

solution with a bitter taste and a slippery feel

Weak

strength of a base that only partly ionizes in solution

Hydrocholoric Acid

what is HCl

Concentration

dilute and concentrated refer to this of a solution, amount of acid or base dissolved in a solution

Base

washing your hands with soap, means you are using a ____

Sulfuric Acid

H2SO4 refers to

Sodium Hydroxide

NaOH refers to

pH lower than 7

include stomach acid, and pickle juice

pH greater than 7

include detergent, blood, and ammonia

pH that equals 7

include pure water

Strength

refers to the ease with which an acid or base ionizes in a solution

Acid

characteristic is sour, produces hydrogen ions, gastric juices in stomach

Base

characteristic is bitter, slippery, produces hydroxide ions, soaps, ionic

Acid and Base

characteristics that form in solutions, are corrosive, dected with an indicator
