"How many grams of salt can be dissolved in 100 ml of water" Dissolution PPT Courseware 2
Experiments are needed to verify. Use data to illustrate.
Different substances have different dissolving abilities in water. So how big is the dissolving ability of a substance in water?
Can you provide exact data on its dissolving capacity?
How can we study the amount of salt dissolved in a glass of water and know the amount of its dissolving power? Ask students to refer to some student dialogue prompts in the text and combine them with the experience of the previous class to come up with experimental methods.
think:
What small problems should we focus on solving?
How to prepare 100ml of water?
How to add salt?
Experimental conditions:
(1), a cup of water (100 ml), 40 grams of salt (30 ml)
(2) Add the same amount of salt (1 part) each time, a total of 10 parts
(4) Wait until the first portion is dissolved before adding the second portion until the added salt can no longer be dissolved.
(5) Calculate how many parts are dissolved until the salt cannot be dissolved, and how many grams it is.
Based on these determined quantities, students compared the research plan in the text to formulate the research plan of their group.
One conclusion can be drawn from today’s experiment——
A certain amount of water can only dissolve a certain amount of salt
The salt water everyone makes now can no longer dissolve table salt. Such a solution is called a saturated solution.
