Baking soda added to water raises the temperature slightly. Chemical reactions are either endothermic or exothermic. Left over heat will raise the temperature. Baking soda and water is exothermic and so the water gets a little warmer.

Sodium bicarbonate and acetic acid reacts to carbon dioxide, water and sodium acetate. The solid baking soda was placed in liquid vinegar producing carbon dioxide gas, which is evident because of the formation of bubbles in the foaming mixture.

The baking powder reacts with water to produce bubbles, while baking soda does not react with water.

Sodium bicarbonate (NaHCO3), also known as baking soda or sodium hydrogen carbonate, is a white powder that readily dissolves in water to produce sodium (Na+) ions and bicarbonate (HCO3) ions. In the presence of acids, these ions create carbon dioxide gas (CO2) and water.

Answer: It became a juice. That is homogeneous or uniform mixture. The powder of the juice will mixed to the water.

Salt water is a solution because it has these two characteristics: it has the same concentration of each of its parts throughout the solution, and it can be separated by some physical process. stands for the element hydrogen, and the O stands for the element oxygen.

True Solution is a homogeneous mixture of two or more materials with a particle size of less than 10-9 m or 1 nm dissolved in the solvent. Example: Simple sugar solution in water. Particles can not be isolated from true solutions by using filter paper which is also not apparent to the naked eye.

True solution is a homogeneous mixture of two or more substances. Particles of true solutions cannot be filtered through filter paper and are not visible by naked eyes. In true solution the particle size of solute is about the same as that of the solvent.

True solution – Salt solution, copper sulphate solution, sugar and water solution, vinegar, air, brass. Colloidal solution – Milk, Blood, Soap solution, starch solution, ink. Suspension – Milk of magnesia, chalk powder and water solution, flour in water, muddy water.

Salt water is a true solution because it dissolves completely in water and it makes a homogeneous mixture .

A Tea is a solution of compounds in water, so it is not chemically pure. It is usually separated from tea leaves by filtration. B Because the composition of the solution is uniform throughout, it is a homogeneous mixture.

Tyndall effect, also called Tyndall phenomenon, scattering of a beam of light by a medium containing small suspended particles—e.g., smoke or dust in a room, which makes visible a light beam entering a window.

When a beam of light is directed at a glass of milk, the light is scattered. This is a great example of the Tyndall effect. When a torch is switched on in a foggy environment, the path of the light becomes visible. In this scenario, the water droplets in the fog are responsible for the light scattering.

The Tyndall effect is scattering of light by particles in a colloid or particles in a fine suspension. It can be seen when the light passes through the colloids or turbid substances causing the light to scatter in multiple directions. Examples are: Light being shined through milk. As milk is a collloid.

Answer: The visible beam of headlights in fog is caused by the Tyndall effect. The water droplets scatter the light, making the headlight beams visible. The Tyndall effect is used in commercial and lab settings to determine the particle size of aerosols.

Tyndall Effect Examples An example of how the Tyndall effect scatters blue light may be seen in the blue color of smoke from motorcycles or two-stroke engines. The visible beam of headlights in fog is caused by the Tyndall effect. The water droplets scatter the light, making the headlight beams visible.

The light is spread when a beam of light is directed at a glass of milk. This is a perfect description of the Tyndall effect. The direction of the light becomes evident when a torch is turned on in a foggy atmosphere. The water droplets in the fog are accountable for the scattering of light in this case.

The Tyndall Effect is the effect of light scattering in colloidal dispersion, while showing no light in a true solution. This effect is used to determine whether a mixture is a true solution or a colloid.

This is because colloids have suspension of small particles, from 1 – 1000 nanometres in size which can scatter light falling on them, a phenomenon called as Tyndall effect. In the above question, only b) milk and d) starch solution show Tyndall effect as they are colloids.

Scattering of light by water droplets in the air. Shinning a beam of flashlight into the glass of milk. One of the most fascinating Tyndall Effect examples is the blue colored iris. The translucent layer over the iris causes the scattering of the blue light making the eyes look blue.

Common salt solution and copper sulphate solution does not show Tyndall effect as they are less than 1 nm in diameter and cannot be seen by naked eye. Due to its small particle size, they do not scatter a beam of light passing through the solution.

-The scattering of light by colloidal solution tells us that the colloidal particles are much bigger than the particles of a true solution. – We can see that the correct options are (B) and (D), milk and starch solution are the colloids, hence these will show the tyndall effect.

The scattering of the light through the colloid is known as Tyndall effect. The sugar solution is not a colloidal solution, the particles in the sugar solution are too small. So, a solution of sugar and water does not show Tyndall effect.

Therefore, tyndall effect will be shown by soap solution above critical micelle concentration. The correct answer is B. Soap solution is colloidal or not depending on kraft temperature and critical micelle concentration. Sugar and sodium chloride solutions are true solutions as they are completely soluble in water.
