Acids+&+Bases

Vocab/Important Terms

 Acid - chemical solution which has a pH lower than 7  Base - chemical solution which has a pH higher than 7  Neutral - chemical solution which has a pH of 7

 Arrehnius acid – ionizes to yield H­­­+  Arrehnius base – ionizes to yield OH-  Bronsted Lowry – consists of H+ donors (acids) and H+ acceptors (base)  Lewis Acid-Base – Acids accept the electron pair while bases donate them

Sample Problems  2. Give the formula of the conjugate acid  a. NH 3  What you do since it is a C Acid is that you would add a H+ molecule  to it with a +1 charge. The answer would be NH 4 + <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;"> b. NH <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 9px; text-decoration: none; vertical-align: sub;">2 <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 9px; text-decoration: none; vertical-align: super;">- <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;"> What you do is that you would add the H+ molecule and charge to the C. Acid so your answer is NH <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 9px; text-decoration: none; vertical-align: sub;">3

Base, you take away a H+ or a hydrogen molecule and that would mean the charge would decrease by one. so the answer would be PO <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 9px; text-decoration: none; vertical-align: sub;">4 <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 9px; text-decoration: none; vertical-align: super;">-3
