A Universal pH chart is a visual tool used to determine the pH level of a solution, indicating its acidity or alkalinity. The pH scale ranges from 0 to 14, with 7 being neutral. Values below 7 indicate acidity, while values above 7 indicate alkalinity. The chart is typically color-coded, with each color corresponding to a specific pH value.
How to Use the Universal pH Chart:
- Obtain a pH indicator: This can be in the form of pH paper strips or a liquid pH indicator solution.
- Test the solution: Dip the pH paper strip into the solution or add a few drops of the liquid indicator to the solution.
- Observe the color change: The pH paper or solution will change color based on the pH level of the solution.
- Compare the color: Match the resulting color to the corresponding color on the Universal pH chart to determine the pH value of the solution.

Balance lever
The best definition of a balance lever is a simple machine that consists of a rigid bar or beam that pivots around a fixed point called the fulcrum. It is used to compare the weights or forces of two objects and determine if they are in equilibrium (balanced) or if one side is heavier than the other (unbalanced).
The balance lever operates on the principle of torque, where the torque (rotational force) exerted on one side of the fulcrum is equal to the torque on the other side when the system is in equilibrium. This principle is expressed by the formula: Torque = Force × Distance from fulcrum.
By placing known masses or weights on one side of the lever and an unknown weight on the other side, the balance lever can be used as a weighing scale. When the lever is in balance, the two sides are equal in weight or force. This concept has been widely used in various applications, from traditional weighing scales to more complex systems like seesaws or construction equipment.
Barlows wheel apparatus
The Barlow's wheel apparatus is an experimental device used to demonstrate the conversion of electrical energy into mechanical energy through electromagnetic principles. It consists of a horizontal wheel or disk with radial metal spokes attached to its center. The wheel is mounted on an axle, allowing it to rotate freely.
beaker hysil
A glass beaker is a cylindrical, open-top container made of glass, typically with graduated volume markings on its side. It is commonly used in laboratories for holding, mixing, and heating liquids, as well as for performing various experiments and chemical reactions. Glass beakers come in various sizes and are designed to provide easy observation of the contents and to withstand temperature changes without significant deformation or chemical interaction with the substances being used.
Beaker Plastic
A plastic beaker is a laboratory container made from plastic material, typically featuring a cylindrical shape with a flat bottom and a spout or pouring lip. It is used for holding, measuring, and mixing liquids or substances during various scientific experiments, research, or educational activities. Plastic beakers come in a range of sizes and are designed to withstand various chemicals and temperatures, making them versatile tools in laboratory settings.
Bernoulli Tube Apparatus
The Bernoulli tube apparatus, also known as a Venturi tube apparatus, is a scientific device used to demonstrate the principles of fluid dynamics, particularly the Bernoulli's principle. It consists of a specially shaped tube with a constricted region, often referred to as a Venturi section. When fluid (liquid or gas) flows through the tube, the constricted section leads to changes in pressure and velocity according to Bernoulli's principle, which states that as the velocity of a fluid increases, its pressure decreases and vice versa. This apparatus is commonly used in educational settings to visually illustrate how the flow of a fluid can affect its pressure, helping to explain various phenomena like lift in aircraft wings, fluid flow through pipes, and more.
