What else can I help you with?
When lactose is mixed with water do you get precipitate?
Lactose is a monosachcharide.They are soluble in water.
What does NaHCO3 change to when dissolved in H2O?
NaHCO3 is sodium bicarbonate (baking soda.) It is water soluble, and in solution it will dissociate into Na+ ions and HCO3- ions.
Why is iodine slightly soluble in water while lactose is very soluble?
Iodine is slightly soluble in water due to its nonpolar molecular structure, which limits its interaction with polar water molecules. In contrast, lactose, a disaccharide composed of glucose and galactose, has multiple hydroxyl (-OH) groups that can form hydrogen bonds with water, making it highly soluble. The polar nature and hydrogen-bonding capability of lactose enhance its solubility compared to iodine.
Is lactose hydrophilic?
Yes, lactose is considered hydrophilic. As a disaccharide sugar composed of glucose and galactose, it has multiple hydroxyl (-OH) groups that can form hydrogen bonds with water molecules, allowing it to dissolve in water. This property makes lactose soluble and able to interact with the aqueous environment in biological systems.
What mass of NaHCO3 is needed to neutralize 150ml of 044M HCl?
Several part problem. Get molarity of NaHCO3. (150 ml)( M NaHCO3) = (150 ml)(0.44 M HCl) = 0.44 M NaHCO3 --------------------------- get moles NaHCO3 ( 150 ml = 0.150 Liters ) 0.44 M NaHCO3 = moles NaHCO3/0.150 Liters = 0.066 moles NaHCO3 ---------------------------------------get grams 0.066 moles NaHCO3 (84.008 grams/1 mole NaHCO3) = 5.54 grams NaHCO3 needed ---------------------------------------------answer
Is lactose soluble in NaOH?
Yes, lactose soluble is NaOH. Sodium is Na always and is water soluble. The website Study Mode has many examples of experiments done to prove that lactose is soluble.
Is sodium bicarbonate (NaHCO3) soluble in water and therefore considered an aqueous solution?
Yes, sodium bicarbonate (NaHCO3) is soluble in water and forms an aqueous solution.
When lactose is mixed with water do you get precipitate?
Lactose is a monosachcharide.They are soluble in water.
What does NaHCO3 change to when dissolved in H2O?
NaHCO3 is sodium bicarbonate (baking soda.) It is water soluble, and in solution it will dissociate into Na+ ions and HCO3- ions.
Does lactose dissolve in water?
Yes, lactose does dissolve in water. Lactose is a water-soluble carbohydrate found in milk and dairy products. When mixed with water, lactose molecules break apart and disperse, allowing them to dissolve in the liquid.
Is salicylic acid miscible in Naoh nahco3 and Hcl?
Salicylic acid is soluble in NaOH and insoluble in NaHCO3 and HCl. In NaOH, salicylic acid can form a salt through neutralization. In NaHCO3 and HCl, salicylic acid remains as a solid due to its low solubility in these solutions.
Is lactose polar or non-polar?
lactose is polar, it can dissolve in water, hense the blood stream
Why is 2-naphthol insoluble in NaHCO3?
2-naphthol is insoluble in NaHCO3 because it is a weak acid and can only partially ionize in solution. Therefore, it does not interact strongly with the bicarbonate ions in NaHCO3 to form a soluble salt.
Is hydrogen carbonate soluble?
Yes, hydrogen carbonate (bicarbonate) is soluble in water. It dissolves readily to form a solution.
How lactose is formed from monosaccahrides?
Monsaccharides are a simple for a sugar and can have a sweet taste. They are usually colorless and water-soluble. Monosaccharide includes glucose and galactose. Lactose is made from both of those at its simplest forms.
What happen when NaHCO3 plus HCl?
When sodium bicarbonate (NaHCO3) is mixed with hydrochloric acid (HCl), a chemical reaction occurs where carbonic acid (H2CO3) is formed. This then decomposes into water and carbon dioxide gas. The reaction produces bubbles of carbon dioxide gas, creating a fizzing or effervescent effect.
How do you differentiate between a sodium bicarbonate solution a calcium carbonate and one with both?
Sodium bicarbonate (NaHCO3) is soluble in water; calcium carbonate (CaCO3) is practically insoluble in water.
