LAST TEST EVA

Question 1

characteristics of acids

Answer 1

sour, on blue litmus turns red, on red litmus turns keeps same color, PHTH doesnt change color, metals H2, Baking Soda CO2, feels like water

Question 2

characteristics of bases

Answer 2

bitter, slippery, blue on red litmus, nothing on blue litmus, pink with PHTH

Question 3

Arhenius

Arhenius Acid and Base

Answer 3

Acid: has a H upfront, (donates Hplus)
Base: OH- attatched (donates OH-)

Question 4

Bronsted Lowrey Base and Acid

Answer 4

Acid: donates protons
Bases: accept protons

Question 5

Naming Binary Acids

Answer 5

hydrogen and nonmetal

ine-ic
ur-uric

hydro____ic/uric acid

Question 6

naming oxyacids

po

Answer 6

polyatomic anion and hydrogen bond
ate-ic
ite-ous

nitrous acid

Question 7

how to identify base, conj base, acid, conj acid

Answer 7

H3O+ always acid
OH- always a base
if it has H upfront its an acid (unless there is a - if so check other side to see if still higher exponent if not then its a base ex. - and 2-)
if - then base

Question 8

c

concentration

Answer 8

amount of solute in the solution

Question 9

what does it mean if an acid or base is strong on the particle level

Answer 9

it has strong conductivity

Question 10

what does it mean if an acid or base is weak on the particle level

Answer 10

it has weak conductivity

Question 11

strong

Answer 11

completly ionizes, conducts electricity very well

Question 12

weake

Answer 12

partially ionizes

Question 13

concentrated

Answer 13

high molarity, high solute

Question 14

dilute

Answer 14

low molarity, high solvent

Question 15

Dilution remember with v1 and stuff

Answer 15

for v2 remeber its V2 plus water, subtract from original if finding water

Question 16

measuring pH

Answer 16

1-anything less than 7 = acid
7=neatrual
above 7 - 14 = base

Question 17

Indicators

Answer 17

changes color of the solutions (weak acids), one color is acids, different color is bases
determines if a solution is a acid or base

Question 18

PHTH indicator

Answer 18

pink with bases
colorless with acids

Question 19

steps to do Ka problems

Answer 19

solve for x when top of equation is x2

x divided by HA to get 5 percent rule

use pH equation to get and plus in og anwser to equation (next to minus log) to get pH

Question 20

how to write products for neutralization reaction problems

Answer 20

H2O + other two elements put together

(split each reactant in hald to see which to add to product)
then once got element balence charges then balence equation

Question 21

How to write a chemical equation with arhenius model acid and base

Answer 21

if has H upfront: is acid: reactants will be H3O+ and what element is left

if there is no H upfront: is base: reactant will be OH- + whatever is left

Question 22

difference between pH and pOH

Answer 22

pH: 1-7 acid, 7 neautral, 7-14, basic
pOH:1-7 basic, 7 neautral, 7-14, acid

so if acidic has low pH and high pOH
so if basic has low pOh and high pH
