What characteristic of water will remain the same regardless of what may be dissolved in it?
a.the ratio of hydrogen to oxygen
b.the freezing temperature
c.the ability to refract light
d.the hydroxide ion concentration
i think its a?
a is the best answer. Hydrogen and Oxygen are not in water. Hydrogen atoms and oxygen atoms are in water. Hydrogen and oxygen are gases.
thanks bob
To determine the characteristic of water that remains the same regardless of what may be dissolved in it, we need to consider the properties of water.
a. The ratio of hydrogen to oxygen: This ratio remains constant in water, regardless of what substances are dissolved in it. Therefore, the answer is correct. The chemical formula of water is H2O, indicating that it consists of two hydrogen atoms and one oxygen atom.
b. The freezing temperature: The freezing point of water can be affected by impurities or substances dissolved in it. For instance, the addition of salt can lower the freezing point of water. Therefore, the freezing temperature is not a characteristic that remains the same.
c. The ability to refract light: The ability of water to refract light is influenced by the substances present in the water. Different dissolved substances can alter the refractive index of water, affecting its ability to refract light. Therefore, this is not a constant characteristic.
d. The hydroxide ion concentration: The hydroxide ion concentration in water can change depending on the substances dissolved in it. It is influenced by the presence of acids or bases. Thus, this is not a consistent characteristic either.
Therefore, the correct answer is indeed a. The ratio of hydrogen to oxygen remains the same regardless of what may be dissolved in water.
