What are true statements about water?
Pure water has a neutral pH of 7, which is neither acidic (less than 7) nor basic (greater than 7). The water molecule is highly cohesive — it is very sticky, meaning water molecules stick to each other. Water is the most cohesive among the non-metallic liquids.
Which of the following statements about water molecule is true?
The correct answer is Water is a nonpolar molecule. Water is a polar molecule: Water is a polar molecule. While the overall charge of the molecule is neutral, the orientation of the two positively charged hydrogens (+1 each) at one end and the negatively charged oxygen (-2) at the other end give it two poles.
Which of the following statements about the water is false?
Water can act both as an acid and as a base. There is extensive intramolecular hydrogen bonding in the condensed phase. Water is oxidized to oxygen during photosynthesis. …
Which one of the following is not true for water?
The answer is C. Water is a very good solvent for non-polar molecules.
Which of the following statements regarding the oxygen atom of a water molecule are true?
The answer is A. Oxygen is more electronegative than the hydrogen atoms. The high electronegativity of oxygen with respect to hydrogen, the oxygen side of the water molecule has a partially negative charge while the hydrogen sides have a partially positive side.
Does water have high cohesion?
Water is highly cohesive—it is the highest of the non-metallic liquids. Water is sticky and clumps together into drops because of its cohesive properties, but chemistry and electricity are involved at a more detailed level to make this possible.
Which of the following is not likely to be soluble in water?
Hydrogen is a gas and not soluble in water. Because a hydrogen molecule is a non-polar compound and water is a polar molecule. We know that ‘like dissolves in like’ . So, hydrogen is not going to soluble in water.
Which statement best explains why nonpolar substances have low solubility in water?
Which statement best explains why nonpolar substances have low solubility in water? They are much larger than water.
Which of the following liquids do not mix with water?
Oil and water are said to be “immiscible,” because they do not mix. The oil layer is on top of the water because of the difference in density of the two liquids. The density of a substance is the ratio of its mass (weight) to its volume. The oil is less dense than the water and so is on top.
Which one of the following is soluble in water?
Ethanol (C2H5OH) forms hydrogen bonding with water. Hence, it is solube in water.
Which one of the following is most soluble in water?
Methanol would have the highest solubility in water since it contains the smallest hydrophobic portion in its…
What is water soluble?
Things like salt, sugar and coffee dissolve in water. They are soluble. They usually dissolve faster and better in warm or hot water. Pepper and sand are insoluble, they will not dissolve even in hot water.
