- When an ionic compound is dissolved in water, each ion is surrounded by a sphere of water molecules called a?
Step by step
Solved in 2 steps
- Using a pH meter, you find the pH of an unknown solution to be 8.0. How would you describe this solution? a. weakly acidic b. strongly acidic c. weakly basic d. strongly basicDescribe the way an ionic solid dissolves in waterWhat, if anything, is wrong with the following statement: “When NaCl is dissolved in water, the water molecules closest to the ions will tend to preferentially orient themselves so that their oxygen atoms face the sodium ions and face away from the chloride ions”? Explain your answer.
- When comparing pH, a solution with a pH of 5 contains 100 times the amount of H+ when compared to a solution with a pH of 7.Solution A is a strong acid of pH 2, and solution B is an equally strongbase of pH 8. Each chemical can donate or receive a single proton. Ifequal amounts of solutions A and B are mixed, is the resulting solution acidic or basic?If a solution has a concentration of 10^-7 OH ions, how many H ions does it have?
- A solution has a hydrogen ion concentration of 0.01 mol/L. What is its pH? What is its hydroxide ion concentration? Is it acidic, basic, or neutral? How does the hydrogen ion concentration of this solution differ from one with a pH of 1?The PH formula is given as PH=-log(H+). The H+ is the number of free ions of hydrogen. A seven PH is considered neutral. Discuss what having a low PH and a high PH means. What does a 12 PH mean? How about a 2? Which is more caustic? Is either a good thing at extremely high or low values? Explain fully as to what a PH means to you and what you use it for.The slight positive charge of a hydrogen atom in one water molecule is drawn to the slight negative charge of an oxygen atom in another. This interaction is known as a(n)
- Ibuprofen, widely used as a pain reliever, has limited solubility in water, less than 1 mg>mL. Which part of the molecule’s structure (gray, white, red) contributes to its water solubility? Which part of the molecule (gray, white, red) contributes to its water insolubility?In mixing compounds with water, the polarity of the compounds helps predict their solubility. When a compound's electrons are shared ; if shared unevenly, the compound is evenly, the compound is said to be .Which group dissolves more readily in waterWhat type of chemical bond forms between hydrogen and oxygen atoms within a water molecule? Which type of chemical bond forms between water molecules, binding them to one another?
