Question:is acetic acid another work for the baking soda and vinegar chemical reaction? also, if you know more SIMPLE (around something that a 5th grader would understand) things about the baking soda and vinegar chemical reaction. kk thankuuu.
Answers:vinegar is a approx 4% solution of acetic acid sometimes known as ethanoic acid when mixed with sodium bicarbonate(baking soda) it turns to sodium acetate and carbon dioxide gas which bubbles off
Answers:Well the reaction between acetic acid in the vinegar and sodium bicarbonate in the baking soda is:
NaHCO3 + CH3COOH CH3COONa + H2O + CO2.
There may be other fun things going on in these impure materials!
Question:Identifying unknown substances using physical and/or chemical properties.
Which physical and chemical properties did you examine?
Behavior in water
Behavior in acid
Identity of solid
Also some possible sources of error?
Materials: 1) Safety Goggles
2) Original containers for; salt, baking soda, chalk, sodium, nitrate, and sodium sulphate.
3) Numbered samples of five unknown solids
4) Toothpicks/wooden splint
5) Hand lens
6) Spot plate or microtray
7) Medicine dropper
8) Small beaker with distilled water
9) Small beaker with dilute hydrochloric acid (3-5%)
Procedure: 1) Put on your safety goggles.
2) Observe each of the properties of the 5 different unknown substances and record your observations. (Do not touch nor smell the chemicals.)
3) Pick up each substance, using the tip of your wooden splint and place each numbered sample, into a different well of the spot plate.
4) Add 4 drops of water to each sample, using a medicine dropper and stir each of them gently. Rate the solubility of each sample and record your information.
5) Repeat step 4) using acid in place of water. Record your observations.
Thanks! And any suggestions to making the procedure better?
Answers:Your procedure should be in past tense.
Answers:Baking soda is sodium bicarbonate, and Vitamin C is ascorbic acid. So isn their reaction we get sodium ascorbate ,carbon dioxide & water
Preparation Of Washing soda And Baking Soda :Check us out at www.tutorvista.com Washing soda is chemically known as sodium carbonate. It is also referred to as soda ash or soda crystals. Washing soda is a sodium salt obtained from carbonic acid and is found in the form of a white powder. It is mostly found in a crystalline form as a heptahydrate (with seven molecules of water). When exposed to air, it loses the water molecules to form a monohydrate. When it dissolves in water, it is broken down to release ions of sodium and carbonate. Let's have a look at some of the main uses of washing soda. Sodium bicarbonate is the chemical compound with the formula NaHCO3. Because it has long been known and is widely used, the salt has many other names including sodium hydrogen carbonate, sodium bicarb, baking soda, bread soda, cooking soda, bicarb soda, saleratus or bicarbonate of soda. It is soluble in water. This white solid is crystalline but often appears as a fine powder. It has a slight alkaline taste resembling that of sodium carbonate. It is a component of the mineral natron and is found dissolved in many mineral springs. It is also produced artificially.
Mixing the ingredients for a Baking Soda Volcano :The baking soda and vinegar volcano is a chemistry project you can use to simulate a real volcanic eruption, as an example of an acid-base reaction, or can do simply because it's fun. The chemical reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid) produces carbon dioxide gas, which forms bubbles in the dishwashing detergent. The chemicals are non-toxic (though not tasty), making this project a good choice for scientists of all ages.
