What is the colour change when turmeric indicator is added to vinegar?
When turmeric indicator is added to vinegar, which is acidic, it changes color from yellow to a reddish-brown. This color change occurs because turmeric contains curcumin, a compound that reacts to changes in pH. In acidic environments, curcumin undergoes a structural change, resulting in the distinct color shift.
How does vinegar make a chicken egg increase in size?
a chemical reactions occurs between the egg shell and the vinegar.
What happend when calcium is adedd to turmeric?
When calcium is added to turmeric, a chemical reaction occurs that can change the color of turmeric from its natural yellow to a reddish-brown hue. This is due to the interaction of calcium ions with curcumin, the active compound in turmeric, which alters its chemical structure and color properties. This reaction is often used in cooking and food science to demonstrate the pH sensitivity and color-changing abilities of turmeric.
What is the chemical process that occurs when vinegar reacts with rust?
When vinegar reacts with rust, a chemical process called oxidation-reduction occurs. This process involves the transfer of electrons between the iron in the rust and the acetic acid in the vinegar, leading to the formation of iron acetate and the removal of the rust from the surface.
Does aluminum react with vinegar?
Yes, aluminum does react with vinegar. When aluminum comes into contact with vinegar, a chemical reaction occurs that produces hydrogen gas and forms aluminum acetate.
What is the chemical reaction between vinegar and rust?
When vinegar reacts with rust, a chemical reaction occurs where the acetic acid in vinegar breaks down the iron oxide in rust, forming iron acetate and water. This reaction helps to dissolve and remove the rust from the surface.
Do milk and vinegar create a chemical reaction?
Yes, when you add an acid, like vinegar, to milk a chemical reaction occurs. The acid causes milk to curdle. In fact, by adding vinegar to milk you can make cheese! http://www.wikihow.com/Make-Cheese-at-Home
Is vinegar form carbon and water mixed with baking soda physical?
No, it is a chemical change. A chemical reaction occurs when the two are mixed-- bubbling/fizzing.
What explodes with baking soda?
When baking soda comes into contact with an acid (such as vinegar or lemon juice), a chemical reaction occurs that produces carbon dioxide gas. This gas creates bubbles and foaming action, causing the explosion-like effect often seen in homemade volcanoes or baking recipes.
Is this a physical or chemical change when you pour vinegar into baking soda?
This is a chemical change because a chemical reaction occurs, creating a whole new substance (carbon dioxide).
What happens when citric acid and vinegar react with each other?
When citric acid and vinegar react with each other, a chemical reaction occurs that produces carbon dioxide gas. This reaction results in the formation of bubbles and fizzing, similar to the reaction that occurs when baking soda and vinegar are mixed together.
What is the chemical reaction that occurs when vinegar and baking soda are combined, and what are the products formed as a result?
When vinegar (acetic acid) and baking soda (sodium bicarbonate) are combined, a chemical reaction occurs that produces carbon dioxide gas, water, and sodium acetate. This reaction is known as an acid-base reaction, where the acetic acid in vinegar reacts with the sodium bicarbonate to form carbon dioxide gas, water, and sodium acetate.
