Whether it is possible to make solid substance of liquid? The answer will be affirmative if to mix available substances in the necessary proportions. Having prepared chemical compound before arrival of friends it is possible to surprise them with unusual transformation of liquid into firm balls.
It is required to you
- - baking soda;
- - vinegar;
- - calcium bicarbonate;
- - iodinated salt.
Instruction
1. Make sodium acetate, gradually mixing baking soda and vinegar in small proportions. Fill a soda pinch in a glass, pour a little vinegar, rotate a glass before full mixing. Repeat operation several times, mix extinguished soda a spoon and put for 10 minutes in the fridge. Ready acetate of sodium it has to turn out a third of a glass.
2. Prepare bicarbonate of sodium and iodinated salt, these components are necessary to make firm water balls. With salt of problems at you will not arise, it is on sale in any supermarket.
3. Receive a small amount of bicarbonate of calcium in house conditions, having mixed baking soda and chloride calcium which buy in pharmacy. Formula of chemical reaction: 2NaHCO3+CaCl2 = 2Ca(HCO3) 2 + 2 NaCl.
4. Bicarbonate of calcium can also be received from a carbonate of calcium is a usual chalk. Dissolve chalk in water. Through the received suspension blow carbon dioxide. Gradually chalk will turn into a calcium hydrocarbonate. Filter solution and a vyparta water.
5. Mix the cooled acetate of sodium with a quarter of a glass of bicarbonate of calcium. There will be an impassioned reaction. Measure 110 g of the iodated soda, add to a glass and mix.
6. Put mix on fire. You cook within 7 minutes, constantly stirring slowly. You watch that liquid did not boil away therefore regulate fire in the course of cooking.
7. Pour out liquid in the prepared capacity. Let's cool down within 15 minutes at the room temperature. After that prove to friends that you made firm water balls.
8. Lower fingers in capacity and pull out from it a firm ball or scoop a liquid handful that on a palm there were several water balls. On air the received chemical compound turns into solid substance. Once you lower transparent balls in capacity, they become liquid again.
