Question

Biology lab

1. A chemist created a solution with a PH of 6.3. The solution needed to be within a range of 7.3 - 7.5 for human consumption. What must the chemist do to make the solution acceptable?

##.A student needed to identify a product that had ionic bonds in nature and covalent bonds in nature. What two substances she can use to achieve her goal?

# .An intern was given a polysaccharide and was asked to create a disaccharide and monosaccharide. What product the intern can use to satisfy their lab assignment?  

Answer 1

1). Distilled or pure water has a 7 pH, which means both are the neutral solution.   If we have to increase the pH of any solution, we must have to add an alkaline solution or substance, such as NaOH (sodium hydroxide). Or if we have lower the pH, then we have to add an acidic solution or substance such as lime or lemon juice to it. So the chemist can add some alkaline substance to its prepared solution to make it in a range of 7.3 to 7.5 for the consumption of humans.

2). The products with ionic bonds can be dissolved in the water and are the good conductor of the electricity whereas the covalent compounds are not a water-soluble and bad conductor of the electricity. With the help of water and electricity, the student can easily identify the ionic and covalent compounds.

3). Hyaluronic acid, chondroitin, and heparin are the examples of heteropolysaccharides which are made up of repeating units of mono or disaccharides. From these compounds, an intern can create a monosaccharide as well as a disaccharide.
