I just need someone to check my answers please :)
On the pH scale are the following items base, neutral, or acid?
1. Hand Soap
2. Blood
3. Milk
4. Coffee
5. Orange Juice
6. Soda Pop
7. Vomit
8. Battery Acid
My answers:
1. Base
2. Neutral
3. Neutral
4. Neutral
5. Base
6. Acid
7. Acid
8. Acid
To determine whether each item on the pH scale is a base, neutral, or acid, you can use a pH indicator or a pH meter. However, in the absence of those tools, you can make some rough estimations based on general knowledge.
1. Hand Soap: Typically, soaps are basic in nature. So, this is likely a base.
2. Blood: Blood has a neutral pH of around 7, making it neutral.
3. Milk: Milk is slightly acidic, with a pH ranging from 6.5 to 6.7. So, it is slightly acidic, but closer to neutral.
4. Coffee: Coffee is generally considered acidic, with a pH ranging from 4.5 to 6. Therefore, it is likely acidic.
5. Orange Juice: Orange juice is acidic due to the presence of citric acid, so it is likely acidic.
6. Soda Pop: Most sodas are highly acidic, mainly due to carbonic acid formed by carbonation. So, it is likely acidic.
7. Vomit: Vomit is typically acidic, as it contains stomach acid. So, it is likely acidic.
8. Battery Acid: Battery acid is highly acidic, with a very low pH level. So, it is definitely an acid.
Your answers:
1. Hand Soap: Base - Correct
2. Blood: Neutral - Correct
3. Milk: Neutral - Incorrect, it is slightly acidic
4. Coffee: Neutral - Incorrect, it is acidic
5. Orange Juice: Base - Incorrect, it is acidic
6. Soda Pop: Acid - Correct
7. Vomit: Acid - Correct
8. Battery Acid: Acid - Correct
Most of your answers are correct, except for milk, coffee, and orange juice. Milk is slightly acidic, coffee is acidic, and orange juice is also acidic. Remember, if you are uncertain about the pH of a certain substance, it's always best to verify using a pH indicator or a pH meter.
