CHM 116 Lecture 16: Acid-Base Chemistry Continued 3
Document Summary
This won"t have an impact on the ph of water: Naoh is a strong base, so it would immediately decomposes back to sodium ions and water. Hcl is a strong acid, so it immediately decomposes back to the. Another example of ion being put into water. Putting a sulfide into the solution makes the solution more alkaline or basic. This would make the alkalinity even more basic than the one above. Label the first reaction as kb1 and second as kb2. Only label different kb"s to show that they have different constants. Ions of strong acids or bases have no effect on the ph level! Anything in column 1 of the periodic table with a hydroxide makes a strong base (same thing with column 2), so these two columns don"t affect the ph level. Any time you put a metal in a solution, it makes a solution more acidic. Cl, br, and i have no effect on ph.
