Question

question 31 1 pts as the concentration of hydrogen ions increases, the ph goes __, and the solution becomes more __. down; acidic down; alkaline up; acidic up; alkaline question 32 1 pts acids, bases, and salts belong to a large group of compounds called polar molecules. organic compounds. electrolytes. nonelectrolytes. question 33 1 pts the total number of electrons in a neutral atom equals the number of: neutrons orbiting the atom. protons plus the number of neutrons in its nucleus. protons in its nucleus. ions in its nucleus

Explanation:

• For Question 31: The pH is defined as $pH = -\log[H^+]$. As the hydrogen - ion concentration $[H^+]$ increases, the negative logarithm of it decreases, so the pH goes down. A lower pH indicates a more acidic solution.
• For Question 32: Acids, bases, and salts dissociate in water to form ions and can conduct electricity, so they are electrolytes.
• For Question 33: In a neutral atom, the number of negatively - charged electrons equals the number of positively - charged protons in the nucleus to maintain electrical neutrality.

Answer:

Question 31: A. down; acidic
Question 32: C. electrolytes
Question 33: C. protons in its nucleus
