 * Research Question: What is the effect of location of the water source on pH, ammonia, and nitrate concentrations on tap water. **




 * Hypothesis: Yangming Shan water will be closer to distilled H2O than Downtown or Nangang**


 * Independent Variables **
 * **Yangming Shan tap water**
 * **Downtown tap water**
 * **Nangang tap water**


 * Dependent Variables **
 * **pH**
 * **Ammonia concentration**
 * **Nitrate concentration**


 * Ammonia **
 * **Effects**: Humans actually produce ammonia, but it low concentrations, so ammonia is only harmful in higher concentrations. When an excess amount of ammonia enters the body, it will damage cells in the body. It is poisonous when swallowed, extremely irritating to respiratory passages, and can burn your mouth, throat, and stomach. When too much ammonia is ingested, it can result in death.
 * **Standard Amount**: The standard amount of ammonia in Taiwan tap water is 0.1 milligrams/liter
 * **Method**: we will use an ammonia probe
 * **Results**:
 * || **dH2O (control)** || **Yangming Shan** || **Downtown** || **Nangang** ||
 * **Ammonia Concentration (mg/L)** || 0.0 || 0.2 || 0.6 || 0.4 ||


 * Nitrate **
 * **Effects**: When nitrate enters your body, it replaces the oxygen in your hemoglobin, causing a lack of oxygen in your blood. This results in a syndrome in babies called "blue baby syndrome," which makes babies' skin turn blue as a result of lack of oxygen.
 * **Standard Amount**: The maximum limit of nitrate that is considered harmful is 10 milligrams/liter
 * **Method**: we will use a nitrate probe
 * **Results**:
 * || **dH2O (control)** || **Yangming Shan** || **Downtown** || **Nangang** ||
 * **Nitrate Concentration (mg/L)** || 0.1 || 0.9 || 1.5 || 1.1 ||


 * pH **
 * **Effects**: pH of pure water is about 7, but drinking water is normally a bit lower, around 6.5 Low levels of pH in water could mean there are toxic heavy metals in the water, such as iron, manganese, copper, lead, and zinc.
 * **Standard Amoun**t: In Taiwan, the standard pH of water is 7.1
 * **Method**: we will use a pH probe
 * **Results**
 * || **dH2O (control)** || **Yangming Shan** || **Downtown** || **Nangang** ||
 * **Trial 1** || 6.59 || 6.63 || 7.34 || 7.35 ||
 * **Trial 2** || 6.61 || 6.79 || 7.43 || 7.41 ||
 * **Trial 3** || 6.54 || 7.11 || 7.44 || 7.47 ||
 * **Trial 4** || 6.56 || 7.14 || 7.47 || 7.45 ||
 * **Trial 5** || 6.50 || 7.04 || 7.38 || 7.51 ||
 * **Average** || 6.56 || 6.93 || 7.41 || 7.44 ||
