    In every home's refrigerator, pantry, and even a drawer full of waste products, there are actually a lot of treasures of scientific experiments. This book will introduce you to 52 fun and educational experiments that you can use to explore science with what you already have at home. In the spring, you can learn biology by planting on a windowsill.

    On a snowy winter day, try your hand at a fun ice cube experiment and learn why snow plows sprinkle salt on icy roads. Or maybe you happen to have a box of cornstarch on your hand, and you can simply add water to make a non-Newtonian fluid, which is a lot of fun. Children will find that science is not difficult at all, nor is it scary at all, science is everywhere.

    These experiments are safe enough for younger children and attractive enough for older children that they can be carried out using materials readily available at home. Each experiment in the book contains 5 parts: experimental materials, safety tips, experimental procedures, scientific secrets, and whimsical ideas, all of which are as simple and straightforward as recipes.

    Vinegar and soda. When you slowly add the soda to the glass that has been poured into the vinegar bush beforehand, a large amount of gas will be released, and a large amount of foam will be generated, just like when the beer is poured (if it is accelerated, the foam may overflow).

    The reaction equation is as follows

    2hoac Na2CO3 ==2Naac H2O CO2 (gas) or. Hoac NaHCO3 ==Naac H2O CO2 (gas).

    Cu and Cl2 Cu + Cl2 = = Ignition == CuCl2

    Fe and Cl2 3Cl2+2Fe = = 2FeCl3

    H2O and Cl2 Cl2+H2O = HCl+HCl

    H2 and Cl2 H2 + Cl2 = Ignition = 2HCl

    CH3COOH and FE2CH3COOH+ FE= FE(CH3COO)2+ H2

    CH3COOH and CAC3 CAC3+2CH3COOH=CA(CH3COO)2+CO2+H2O

    CH3COOH and NAOH CH3COOH + NAOH = CH3COONA + H2O

    The kitchen contains salt, ethanol, acetic acid and other substances, a to test the content of alcohol using titration, can be identified by potassium permanganate or potassium dichromate, can not be completed in the kitchen, so a is wrong;

    b The iodine element potassium iodate in the experiment exists in the form of potassium iodate, which needs to be tested by potassium iodide starch test strip, so b is wrong;

    c can be used to detect chloride ions with silver nitrate, which cannot be completed in the kitchen, so c is wrong;

    d The egg shell can be dissolved with acetic acid, which can be completed in the kitchen, so d is correct so choose d

Because oxygen is a chemically reactive gas, there are many other gases in the air, and if you can get all the other gases out, then you can measure the volume fraction of oxygen, but obviously there is no red phosphorus in the textbook. It consumes only oxygen, less oxygen, so the volume of water replenished can be considered to be the volume of oxygen.
