Sodium bicarbonate increases the antiseptic action of sodium hypochlorite.
To prepare a saturated sodium bicarbonate solution, add sodium bicarbonate (baking soda) to water until no more can dissolve. This creates a solution where the maximum amount of sodium bicarbonate is dissolved in the water.
Yes, because sodium bicarbonate solution is basic.
Yes, sodium bicarbonate (NaHCO3) is soluble in water and forms an aqueous solution.
Cholesterol is not very soluble in sodium bicarbonate. However, in a basic solution, such as sodium bicarbonate, cholesterol forms some salts that are more soluble.
If phenol red is added to sodium bicarbonate, the color of the solution will change based on the pH. In an acidic solution, phenol red will appear yellow, in a neutral solution it will be red, and in an alkaline solution (such as when sodium bicarbonate is added), it will turn a pink or magenta color.
Sodium bicarbonate, NaHCO3 is alkaline so the pH will be greater than 7. However, the actual pH will depend on the concentration of the NaHCO3 solution.
hot sodium bicarbonate
By dissolving in water the necessary quantity to obtain the desired concentration of sodium bicarbonate.
********
dilute sodium hydroxide solution
To prepare a 1 N solution of sodium bicarbonate, dissolve 84 grams of sodium bicarbonate in enough water to make 1 liter of solution. This will give you a 1 N (equivalent to 1 mol/L) concentration.
pH paper would change from red to yellow when sodium bicarbonate is added because sodium bicarbonate is a base and would increase the pH of the solution.
