Cooks use baking soda to make cakes light and fluffy. you might have used baking soda yourself. baking soda is nahco3. a 0.1 m solution of baking soda and water has a [h+] of about 4.0 x 10^-9. (you may prefer to think of the hydronium ion concentration, [h3o+], as 4.0 x 10-9.) write the formula for the calculation of ph, and then show each job as you calculate the ph of 0.1 m solution of baking soda.,

Answer is: pH = 8,046.
c(H₃O⁺) = 4·10⁻⁹ M = 4·10⁻⁹ mol/L = 0,000000004 mol/L.
pH = -logc(H₃O⁺).
pH = -log(4·10⁻⁹ mol/L).
pH = -(-8,046) = 8,046.
When pH is less than seven (pH<7), solution is acidic.
When is equal seven (pH = 7), solution is neutral.
When pH is greater than seven (pH > 7), solution is basic (like this example).

thats how its supposed to be

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.
