Reactions of Acids Lab

Purpose:
To see how pH idea can be used to identify an virulent
To hold a neutralization reaction
To observe reactions of acids and metals
To observe reactions of acids and carbonates/hydrogen carbonates
To practice making observations, and designing selective information tables

Safety
Do not breath directly whatever solutions in chemistry! If something is to be smelled (and nothing is in this lab) you should use the wafting technique previously demonstrated.
Use forceps and spatulas for dispensing solids! Not your fingers!
muffle your hands when finished
Where splash goggles and aprons

Materials:
Reagents
0.5 M HCl and 6.0 M HCl
0.



5 M NaOH
Sodium bicarbonate
Sodium carbonate
Calcium carbonate
Magesium carbonate
Potassium bicarbonate
Copper
Magnesium
Iron
Zinc
Phenolphthalein & other indicators
Neutral, red, macabre litmus makeup
pHydrion paper
Glassware and other materials
Stirring rod
2 50-mL Erlenmeyer flasks, stoppered
1 100-mL beaker to hold test tube
Forceps
Microplate w/ cap and rubber tube
2 plastic pipets
2 test tubes
metal spatula
wood splint

Clean-up:
1. underprice the well plates upside down onto paper towel in the bin provided to collect metals
2. Rinse the microplate with water and leave to prohibitionist upside down on a piece of paper towel.
3. Return all other materials to basket
4. Get checked for a clean-up sticker

Procedures: Part A: pH paper
Overview: Acids and bases are identified by using pH paper, litmus paper and indicators. In this break apart you are going to test 5 liquids (a weak acid, ironlike acid, weak base, strong base, and water) with 4 different kinds of pH paper and 4 different indicators.
1. Obtain a flask of HCl and a glass stirring rod
2. Wet the stirring rod with acid and carefully...If you want to get a full essay, order it on our website: Orderessay
