A Vibrant Magic Trick Using Bases And Acids?

This video explores the chemistry behind magic tricks, specifically with acids, bases, and indicators. It teaches students how to create pH indicator solutions using cabbage juice and test chemicals. The trick is based on scientific principles rather than actual magic and can be replicated at home with some chemistry knowledge. Tyler, a student at MIT, explains the science behind this magic trick.

The secret of this magic color change is pH, which determines the acidity or basicness of a chemical. Acids turn the indicator red or pink, bases turn it blue, green, or yellow, and neutrals turn it blueish or yellow-green. The Chemistry Magic Tricks Kit offers a cool experiment kit that allows students to make color-changing solutions and even turn water into a solid instantly.

In this activity, students are fooled by an acid-base color-changing reaction, learning how chemistry can explain this magical result. Phenolphthalein is an indicator used in this process. Chemicals with low pH (0-6) are acidic, while those with high pH (8-14) are basic. A pH of 7 is neutral, neither acidic nor basic.

The video also discusses the science of macaroni salad and the magic trick with acids and bases. It shows how to concoct a simple duo of household ingredients that changes color as an indicator tells us where a chemical is acid, base, or neutral.

Is bleach an acid or base?

Acidic cleaners are effective for removing mineral deposits, rust stains, and discoloration from metals, while alkaline cleaners are good at breaking down fatty or oily deposits. Chlorine bleach is a base cleaner that removes stains and dyes from clothes and disinfects. Cleaning products at both ends of the pH scale pose risks, as they can corrode human, animal, and plant tissue, and can eat into tissue if mixed with other chemicals.

To avoid these risks, always read the label, use and store safely. Monthind operatives are health and safety trained, with special attention to cleaning products and appropriate PPE. COSHH assessments are completed for every contract and regularly reviewed.

Do acids turn blue or red?

Litmus paper turns blue when exposed to acids, turning red in acidic solutions. It remains blue in neutral substances. It can be used to test a solution’s acidity or alkalinity. Red paper turns red when pH falls below 4. 5, while blue paper remains blue in alkaline conditions. In contrast, red paper remains blue in acidic conditions. The color of blue and red litmus remains unchanged in different conditions.

Do acids turn blue to red?

Acids turn blue litmus paper red when it comes into contact with acids. When placed in an acidic solution, it turns red, while when placed in a basic or neutral substance, it remains blue. This paper can be used to test a solution’s acidity or alkalinity. Under acidic conditions, the paper turns red when the pH falls below 4. 5, while in alkaline conditions, it remains blue. The paper can be used to measure the acidity or alkalinity of a solution.

Is pink acidic or basic?

The phenolphthalein test employs an organic compound that serves as an indicator for the presence of either an acid or a base. In a basic solution, the compound exhibits a pinkish coloration, whereas in an acidic solution, it is colorless. The chemical formula of phenolphthalein is C₂₀H₁₄O₄, comprising 20 carbon atoms, 14 hydrogen atoms, and 4 oxygen atoms. The compound in question has a tendency to dissolve poorly in water; therefore, an alcohol titration is the preferred method of analysis. The addition of an acidic indicator may result in the formation of a white cloud.

Does pH affect color?

PH significantly impacts pigments responsible for fruit, vegetable, and meat color, as well as water-holding capacity and tenderness of muscle foods. Acidic conditions below the typical post-mortem pH improve these properties. Studies have shown that organic acid marination can improve beef tenderness, cooking loss, and bound water content. Additionally, the splitting of pectin chain molecules in neutral solutions can also affect the color of these foods.

Is toothpaste an acid or base?

Toothpaste is an alkaline base that is used to brush the teeth after eating, as it helps to counteract the acidic influence that occurs in the oral cavity. The fundamental composition of toothpaste is derived from tetra sodium pyrophosphate (TSPP), a sequestering agent that removes calcium and magnesium from saliva, thereby preventing the accumulation of tartar on the teeth and functioning as a water-softening agent.

What is the rainbow experiment with acid and base?

This experiment involves adding hydrochloric acid and sodium hydroxide to a glass tube filled with a neutral universal indicator solution. The demonstrator inverts the tube to mix the solutions, resulting in a rainbow of universal indicator. The demonstration takes only a few minutes and is an effective lesson starter or endpoint. The equipment required includes eye protection, a glass tube, rubber bungs, a beaker, dropper pipettes, and a clamp stand.

How to make pH rainbow?

A saturated sodium carbonate solution is combined with a 0. 10 M hydrochloric acid solution and universal indicator, resulting in a spectrum of colors. It should be noted, however, that hydrochloric acid is a corrosive substance that can cause damage to the eyes and skin.

What turns different colors in acids and bases?

Universal indicator changes color when added to a solution, indicating the pH. Acids cause the indicator to change from green to red, while bases cause it to change from green to purple. To demonstrate this, add a universal indicator solution to an acid and a base hidden in “empty” cups. Three clear plastic cups, citric acid, sodium carbonate, universal indicator solution, and water are used. If the indicator solution is not green, it indicates acidic or basic water, which can be replaced with distilled water.

How do you experiment a rainbow?

To create a rainbow, it is necessary to spray water in front of the sun in an area with sufficient sunlight. It is important to ensure that the sun is at a low angle in the sky.

What colors coincide to an acid or base?

The pH of a solution is typically determined using an acid-base indicator, which is a large organic molecule that reacts to changes in hydrogen ion concentration. Most indicators are weak acids, and the most common is found on “litmus” paper, which is red below pH 4. 5 and blue above pH 8. 2. Other commercial pH papers offer colors for every main pH unit, and a Universal Indicator, a mixture of indicators, provides a full range of colors for the pH scale.
