Two spice bottles in the kitchen contain refined salt NaCl alkaline noodles Na2CO3

(1) The carbonate ions in sodium carbonate will react with acid to release gas, while sodium chloride does not have this phenomenon, so it can be distinguished by vinegar at home: take a small amount of solid to be measured and put it in the cup, add vinegar, if there are bubbles, the substance is alkaline, if there are no bubbles, the substance is sodium chloride

2) The sodium carbonate solution is alkaline and the sodium chloride is neutral, so a small amount of solid and clean test tubes can be taken respectively, dissolved with water, and then colorless phenolphthalein test solution is added dropwise, and the solution is red sodium carbonate;

3) Sodium carbonate can react with lime water to generate white calcium carbonate precipitate, sodium chloride does not react with lime water, so a small amount of solid can be taken in a clean test tube, add water to dissolve, and then add clear lime water dropwise, and then become turbid is sodium carbonate, so the answer is: (1) take a small amount of solid to be measured and put it in the cup, add vinegar, if there are bubbles, the substance is alkaline, if there are no bubbles, the substance is sodium chloride

2) Take a small amount of solid and clean test tubes, add water to dissolve, and then add colorless phenolphthalein test solution dropwise, the solution is red sodium carbonate;

3) Take a small amount of solids in a clean test tube, add water to dissolve, and then add clear lime water dropwise, and the turbidity is sodium carbonate
