Which salt is the least soluble in water, and which of the following?
CaF2 : Ksp=3.9 x 10-11 (2) PbCl2: Ksp=1.6 x 10-5 (3) AgCl : Ksp=1.8 x 10-10 (4) Agloz: Ksp=3.1 x 108.
What is the least soluble compound?
Which of the following compounds would be least water-soluble? Answer : Alkane is the least soluble in water because it lacks hydrogen bonding.
How do you know if a salt is soluble?
If two rules seem to contradict one another, the preceding rule will prevail.
- Salts containing Group I elements (Li+, Na+, K+, Cs+, Rb+) are soluble .
- Salts containing nitrate ion (NO3-) are generally soluble.
- Salts containing Cl -, Br -, or I – are generally soluble.
- Most silver salts are insoluble.
Which is more soluble in water sugar or salt?
Some solutes are more soluble than others in a solvent. Sugar, for example, is more easily soluble than salt in water. However, sugar can only dissolve up to a certain amount. In a half liter of 20 degC water, the maximum amount is 1000 grams.Aban 24, 1391 AP
Why is sugar and salt water soluble?
The oppositely charged ends polar water molecules attract ions and pull them away, leading to dissolution. Sugar is made of sucrose molecules, which are more complex and larger than salt ions (see Teacher Background Lesson 1.2).
Is Turmeric dissolve in water?
Turmeric, a plant, is composed of many chemicals. Many of the aromatic compounds found in turmeric are water-soluble, or disperse well in liquids. They are too small to strain out. This is not a rare occurrence. There is no soluble turmeric.
Is glucose soluble in water how can you tell why is this important?
The reason glucose dissolves easily in water is that it contains lots of polar groups that can hydrogen-bond to water molecules. Hydrogen bonds, which are intermolecular forces that determine the structure of molecules such as DNA, proteins, and cellulose, are crucial.
What happens when glucose is mixed with water?
– Water molecules will be attracted to the positive and negative poles in the glucose molecule. – Water molecules will surround each glucose molecule and weaken its bonds to other sugar molecules.
Which biomolecules are soluble in water?
Alcohols and aldehydes form hydrogen bonds with water. Also, compounds containing NH bonds (Fig. 4-4), and molecules containing these groups are more easily soluble in water. Figure 4-3 Types of hydrogen bonds.
