I wanna start off by saying to all the 567 who saw this and have probably had already done the quick check and didn't put the correct answers after you might have failed or got a 100%, wow! You really didn't feel the need to help out huh?😀 (JP). Anyways
Lesson 7: Acids and Bases Science 7 A Unit 3: Chemical Reactions
🌸1. You test a substance using red litmus paper and the paper turns blue. based on these results, is the substance acidic or basic?
👍B. The substance is basic.
💎2. Which factor confirms that a substance is an acid?
👍B. It's pH is lower than the pH of distilled water.
🥝3. An unknown solution is tested using a known indicator whose pH values are shown in the diagram. If the indicator turns bright yellow, what can you conclude about the unknown solution?
👍B. It is slightly acidic.
💸4. A liquid is bitter and slippery. It is most likely_____.
👍C. a base.
All of these answers are correct why would I waste my time putting the wrong answers?😑💖
They are correct BBBC
can someone answer this plz
Female Bob is correct.
To determine whether a substance is acidic or basic, you can perform a simple test using pH indicator papers. In this case, red litmus paper is used. When red litmus paper turns blue, it indicates that the substance is basic.
When a base reacts with a metal, the result is the production of hydrogen gas.
Now, let's fill in the blanks for the properties of acids and bases based on the given words or phrases:
(ACIDS)
- Taste: Sour
- Reaction with metals: Produces hydrogen gas
- Reaction with carbonates: No reaction
- Uses: Fertilizer, household cleaner, and baking soda
- Reaction with litmus paper: Turns blue litmus paper red
(BASES)
- Taste: Bitter
- Reaction with carbonates: Produces carbon dioxide
- Uses: No information given in the provided words or phrases
- Reaction with litmus paper: Turns red litmus paper blue
It seems that the question does not provide information on the uses of bases.
