  • Citric Acid (reactant) has the chemical formula C6H8O7. It is used a lot in food to give food an acidic taste (lemon or lime taste). 
  • Baking Soda (sodium bicarbonate), a reactant has a chemical formula of NaHCO3. Some of its uses are in baking. In baking, the material bubbles and often causes baked goods to rise.
  • Finally, sodium citrate, the product, is in medicines that can help reduce a kidney stone. 

    • This is the chemical reaction between the two. Citric Acid and Baking Soda reacts to form Sodium citrate, water, and carbon dioxide. 

    In the video below, the citric acid and baking soda combined to form sodium citrate, water, and carbon dioxide. Carbon dioxide are bubbles that fizz. This means that a new substance was formed in the reaction. If a new substance is formed, there has to be a chemical reaction that occurred. Since the bubbles are a new substance, I know a chemical reaction occurred.

    Water is 75% of the banana. The sugars are 12% of the banana.

    • Glucose and fructose (reactant): C6H12O6. Glucose is known as grape sugar while fructose is known as fruit sugar.
    • Sucrose (reactant): C12H22O11. Sucrose is known as table sugar.
    • Water (reactant): H20. Water is the universal solvent and has many uses.

    When a banana rots, the chemicals in the banana react with oxygen in the form of oxidation. When the chemicals mix with oxygen, it causes the banana to turn brown. The reaction that causes brownness on the banana is called enzymatic browning. This is when oxygen is in the air and it goes into the chemicals in the banana. This gives bananas a brown pigment known as melanin. Enzymatic browning changes the smell as well, indicating a chemical reaction occurred.

  • Lead Nitrate (reactant) has the chemical formula of Pb(NO₃)₂. It was used to produce pigments for lead paints.
  • Potassium Iodide (reactant) is KI It is used to protect the thyroid gland from radiation injury.
  • The product, lead iodide, is a bright yellow substance at the end of the video that was used a lot as a pigment for yellow paint.

    • 2KI(aq)+Pb(NO3)2(aq) → 2KNO3(aq)+PbI2(s)

    Potassium iodide in water plus lead nitrate in water equals the product (on the right of the arrow).

    This is a chemical reaction because the solid at the bottom of the container was a new substance created from the reactants put together. The product was the solid.

  • Potassium Permanganate, a reactant, has the chemical formula of KMnO4. It is used in many medications for skincare.
  • Sugar ( C12H22O11) is also a reactant used in baking because of its sweet taste.
  • Caustic Soda or sodium hydroxide is a reactant that has the chemical formula NaOH. It is used to manufacture detergents and soaps. 

    • There are two reactions that take place in this experiment:

    MnO4- + e- → MnO4-2
    The left substance is purple and the right substance is green. These combine in the beginning to look like blue. 

    Next we take our last compound and add to it:

    MnO4-2 + 2H2O + 2e- → MnO2 + 4OH-
    The end result here is brown, but because of the small particles, it appears yellow.

    This is a chemical reaction because through the different colors, new substances were created. The colors were new substances being created, making this a chemical reaction. This reaction is so cool to look at because of the reactions that take place.

  • Ammonium Chloride, or NH4Cl, is the reactant. It is used in batteries to mix with something else because it contains water.
  • Water's chemical formula is H20 and is a reactant. It has million's of purposes throughout the world and is the universal solvent, meaning many things, like ammonium chloride, dissolve in it.

    • NH4Cl(s) → NH+4(aq)+Cl-(aq)
    This is the chemical reaction for ammonium chloride and water. AQ means containing water as a solvent. This created an ion and a cation. This is the product.

    This is a chemical reaction because the temperature changed. The temperature dropped in this substance, creating a new substance. Since a new substance was created, it is a chemical reaction. This reaction is endothermic because the two substances dropped in temperature.

  •  Vinegar (Acetic Acid and reactant) is CH3COOH It is used in cooking and cleaning.
  • Baking Soda (sodium bicarbonate and reactant) has a chemical formula of NaHCO3. Some of its uses are in baking. In baking, the material bubbles and often causes baked goods to rise.
  • Sodium acetate , the product, is used to season foods sometimes. 

    • CH3COOH + NaHCO3 = CH3COONa + CO2 + H2O.

    This reaction shows how baking soda and vinegar form sodium acetate, water, and carbon dioxide gas. 

    This is a chemical reaction because three new substances were created in the reaction. Carbon Dioxide, or bubbles were created. Sodium acetate was created as well.
