How can you test for acids and bases?
by using phenolphthalein,litmus paper (red and blue),cabbage,tea,and PH paper or PH meter
What is the colour of tea on pH paper?
Tea is typically acidic with a pH of around 5-6. On pH paper, which typically ranges from pH 1-14, tea would likely show a color indicating acidity, usually in the range of red to yellow.
Plant materials that change colour in acid or alkali?
Red cabbage can change color depending on the pH of its environment, turning red in acidic conditions and blue or green in alkaline conditions. Hydrangea flowers also change color based on soil pH, with acidic soils producing blue flowers and alkaline soils producing pink flowers. Bougainvillea flowers can also change color in response to soil pH levels, with more acidic soils leading to redder flowers and more alkaline soils producing pinker shades.
What can separate tea leaves and water mixture?
A strainer or a tea infuser is commonly used to separate tea leaves from a water mixture when making tea. The strainer is placed over a cup or teapot and the mixture is poured through, allowing the liquid to pass through while trapping the tea leaves.
How do you make sheets of paper look dated?
To make sheets of paper look dated, you can try staining the paper with tea or coffee to give it an aged appearance. You can also lightly crumple the paper and then flatten it out again to create creases and wrinkles that suggest wear and tear. Additionally, you can carefully burn the edges of the paper to give it a weathered look.
