what happens when you put a moth ball in 75-80 degree C tap water?
When you put a mothball in hot tap water at a temperature between 75-80 degrees Celsius, several things may happen. The exact outcome depends on various factors such as the size of the mothball, its chemical composition, and how long it remains in the water. Here is a step-by-step explanation of how you can predict the outcome:
1. Identify the chemical composition of the mothball: Mothballs are typically made of either naphthalene or paradichlorobenzene. Knowing the exact composition will help us understand what occurs when it's exposed to high temperatures.
2. Research the chemical properties of the mothball composition: Naphthalene, for example, has a melting point of around 80 degrees Celsius, while paradichlorobenzene has a higher melting point of about 53 degrees Celsius. Understanding the melting point will help determine if the mothball will dissolve or remain intact in the hot water.
3. Consider the solubility of the mothball: Mothballs are designed to slowly release chemicals into the air to repel insects, rather than easily dissolve in water. Therefore, the solubility of the mothball material isn't very high. However, some small amount may dissolve in the hot water.
4. Predict potential consequences: When you place a mothball in hot tap water, it will start to heat up. As it reaches its melting point, it may partially or completely dissolve, releasing its chemical compounds into the water. This could result in a strong odor and a discoloration of the water. If the water cools down rapidly, the dissolved compounds may precipitate and form solid particles or crystals.
5. Safety precautions: It's important to note that some mothball compounds can be toxic if ingested or inhaled in large quantities. Therefore, it's best to avoid contact with the dissolved mixture and ensure proper ventilation when dealing with mothballs.
To summarize, when a mothball is placed in 75-80 degrees Celsius tap water, it will likely heat up, partially or completely dissolve, release its chemical compounds into the water, and may cause discoloration and odor. However, the exact outcome may vary depending on factors such as the composition and size of the mothball.
