TIPS ON LAB PREPARATIONS

TIPS ON LAB PREPARATIONS:

I HAVE FOUND IT USEFUL TO MIX STOCK SOLUTIONS AND KEEP THEM FROM SEMESTER TO SEMESTER. FOR INSTRUCTIONS ON HOW TO MIX THESE STOCK SOLUTIONS, CONSULT THE TEACHER'S MANUAL FOR THE RESOURCE FROM WHICH THE LAB ORIGINATES. BOTTLES OF THESE SOLUTIONS CAN BE LABELED AND STORED FROM SEMESTER TO SEMESTER.

IF YOU ARE USING THESE RESOURCE MATERIALS AS A GUIDE TO YOUR LESSON PLANNING, THEN YOU WILL WANT TO MIX QUANTITIES OF SOLUTIONS OF THE FOLLOWING SUBSTANCES AND STORE THEM IN LABELED CONTAINERS FOR FUTURE USE.

*LESSON 9: HARD AND SOFT WATER	SOLUTIONS OF: SODIUM CHLORIDE, CALCIUM CHLORIDE, MAGNESIUM CHLORIDE, POTASSIUM NITRATE, MAGNESIUM NITRATE, CALCIUM NITRATE, SODIUM SULFATE, MAGNESIUM SULFATE AND LIQUID DISHWASHING SOAP.
UNIT B: CHEMICAL CHANGE	&NBSP;
*LESSON 9: LAW OF CONSERVATION OF MASS	SOLUTIONS OF: LEAD (II) NITRATE, POTASSIUM IODIDE, COPPER(II) SULFATE PENTAHYDRATE, SODIUM HYDROXIDE, BARIUM CHLORIDE, AND SODIUM SULFATE.
