Calculate the ph of a solution that contains 2.4 × 10 -5 m h 3o at 25°c. 9.38 11.60 4.62 4.17 2.40

4.62.

Explanation:

pH = - log (H+ concentration)

= - log (2.4*10^-5)

= - (-4.6197)

= 4.62.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
