Solutions cont.

Question 1

All ions share the same…

Answer 1

volume

Question 2

How to determine ions in solution

Answer 2

use coefficients of dissociation equation as a ratio

Question 3

STANDARD SOLUTION

Answer 3

a solution has a precise (exact) concentration

Question 4

preparing a standard solution from a solid

Answer 4

c=n/v

Question 5

C with preparing a standard solution from a solid

Answer 5

must be as precise as possible (highest number of sig digs)

Question 6

N with preparing a standard solution from a solid

Answer 6

precise amount of solute particles

Question 7

what is “n” (amount of moles) measured with

Answer 7

centigram scale
converts mass to moles through molar mass

Question 8

V with preparing a standard solution from a solid

Answer 8

precise volume

Question 9

what is volume measured with

Answer 9

a volumetric flask
- has an etched line perfectly calibrated to tenth of a ml

Question 10

DILUTION OF A STANDARD SOLUTION

Answer 10

transfer an exact number of solute particles, “n”, from the standard solution. “n” particles go into a new container, and add water (where the volume increases). a new dilute solution is created

Question 11

C, V, N in standard solution

Answer 11

c inc.
v dec.
n constant

Question 12

C,V,N in dilute solution

Answer 12

v inc.
c dec.
n constant

Question 13

DILUTION EQUATION

Answer 13

C1V1=C2V2
- inverse relationship

Question 14

Answer 14

an element reacting with an aqueous ionic compound in a solution

Question 15

BCR

Answer 15

balanced chemical reaction

Question 16

TIE

Answer 16

total ionic equation

Question 17

NIE

Answer 17

net ionic equation

Question 18

in order from 1-3? NIE, BCR, TIE

Answer 18

BCR
TIE
NIE

Question 19

spectator ion

Answer 19

no change throughout the reaction

Question 20

single replacement has what take place

Answer 20

electron transfer

Question 21

NIR in a double replacement

Answer 21

AX(aq) + BY(aq) —> BX(aq) + Ay(s)
HX(aq) + MOH(aq) —> HOH(l) + MX(aq)

Question 22

double replacement has what take place

Answer 22

no electron transfer
ions crystallize to form a solid
