paper making
Paper sludge is the leftover chemical sludge that is expelled when making paper. This sludge reduces as paper is recycled.
The process of making paper from wood involves both physical and chemical changes. Physically, the wood fibers are mechanically separated and broken down into pulp. Chemically, during the pulping and bleaching processes, chemical reactions occur to alter the composition of the wood fibers and remove impurities, resulting in the transformation of raw wood material into paper.
The most important is sodium sulfite.
Matisse started making paper cutouts when he got cancer.
A chemical change has taken place. The exposure to sunlight causes the paper to undergo a chemical reaction, breaking down the molecules in the paper and causing the color change to occur.
Dipping blue litmus paper in lemon juice is a chemical change. The acidic nature of lemon juice causes a chemical reaction with the blue litmus paper, turning it red. This change in color indicates a chemical transformation of the litmus paper due to the interaction with the acid in the lemon juice.
One way is to treat the paper with chemicals that alter its properties, such as by making it water-resistant or flame-retardant. Another method is to expose the paper to high temperatures or radiation to induce chemical changes. Additionally, incorporating additives or coatings during the paper-making process can modify its chemical properties.
Carbon is the main chemical element found in paper, typically making up about 40-50% of its composition. Other elements present in smaller amounts in paper include hydrogen and oxygen, which are found in cellulose, the main component of paper fibers.
Wax paper is less dense than water, which causes it to float. The wax coating on the paper also helps to repel water, making it more buoyant.
