What is formed when sodium hydroxide solution is put into zinc chloride solution?

Answer 1

There are two reactions.
The first is that a white precipitate of zinc hydroxide is seen.
Because zinc hydroxide is amphoteric, it will react with yet more sodium hydroxide, and the mixture will go clear and colourless again. The final substance formed is called sodium zincate.

For the equations, and the meaning of the word amphoteric, I suggest that you look them up, now that I have given you the necessary reaction outline.

Answer 2

The result can be Zinc Oxide, sodium chloride and Hydrogen.

Answer 3

lots to be executed with them. Make a saturated answer of sodium metasilicate in water, and drop in some colored crystals (the cobalt, copper and iron salts you suggested will artwork properly, and magnesium sulphate ought to be properly worth a shot). After a mutually as, the crystals ought to form stalagmite-like growths. as quickly as the completed technique stops, leave for twenty-four hours, then drain the answer and replace with sparkling water. The cobalt and copper salts have distinctive colours whilst they're moist or dry. Dry them in an oven, then upload somewhat water and see the colour replace. This technique could be repeated. blend citric acid with sodium carbonate powder. CO2 will get carry of off. blend copper sulphate answer with zinc powder. The powder gets a pink coating of copper. blend methylene blue or phenolphthalein with suggestions of the extremely some chemical components, and see the replace in indicator shade. Afterwards, blend the indications and repeat. Then, upload 2 chemical components mutually and see if the indicator adjustments. blend calcium nitrate with sodium sulphate or carbonate. blend sodium tetraborate with a PVA answer. it will turn to slime. blend sodium tetraborate with some sulphuric acid in a around bottomed flask, and stopper with a pitcher tube set by a rubber bung. gently warmth the aggregate with a Bunsen flame till a gas is released, then mild the gas exiting the glass tube. The flame would be a vivid green shade.
