What else can I help you with?
Examples of acids and alkalis?
An acid is a substance which reacts with a base. Commonly, acids can be identified as tasting sour, reacting with metals such as calcium and bases like sodium carbonate Aqueous acids have a pH of less than 7, where an acid of lower pH is typically stronger. Chemicals or substances having the property of an acid are said to be acidic.
What safety equipment must you use when using acids and alkalis?
When working with acids and alkalis, it is important to wear appropriate personal protective equipment such as goggles, gloves, and a lab coat to prevent skin and eye contact. Additionally, working in a fume hood or well-ventilated area can help minimize exposure to potentially harmful vapors.
How can you tell if something is an acid or alkali?
One way to determine if a substance is an acid or alkali is by using pH paper or a pH meter to measure its pH level. Acids typically have a pH below 7, while alkalis have a pH above 7. Another way is to observe its chemical properties, such as its reaction with indicators like litmus paper (turns red in acids and blue in alkalis).
How is science used in the forensic science industry?
In forensic science, scientific principles and techniques are used to analyze physical evidence obtained from crime scenes, such as DNA analysis, fingerprint identification, and ballistics analysis. These scientific methods help investigators solve crimes by providing valuable information that can be used in court to support or refute a hypothesis about a crime.
What should you wear when using acid or alkali?
When using acids or alkalis, it is important to wear appropriate personal protective equipment such as gloves, eye protection, and lab coat to prevent exposure to the skin and eyes. Closed-toe shoes are also recommended to protect your feet.
How can you tell how strong acids and alkalis are using the pH scale?
Acids have a pH under 7, alkalis have a pH bigger than 7.
What three things should you always do when using acids or alkalis in the labrotory?
put safety glasses on

How were alkalis first manufactured on a large scale?
Alkalis were first manufactured on a large scale as Sodium Carbonate in the 1700s using "The LeBlanc Process." This process mixed Sodium Chloride with Sulfuric Acid and then heated with charcoal and limestone. Byproducts included toxic gases Hydrogen Chloride and Hydrogen Sulfide.

Definition of numerical data?
Numerical data is data measured or identified on a numerical scale. Numerical can be analyzed using statistical methods, and results can be displayed using tables, charts, histograms, and graphs.
How do you describe an experiment that allows you to disguish between an acid and alkali without using any indicators?
Acids will react with carbonates to produce a gas (CO2), alkalis won't.Acids will react with magnesium or any active metal but Mg is fast, alkalis won't. An acid + active metal produces hydrogen gas.Acids will clean a coin, alkalis won't.Alkalis feel slimy but acids don't. Only try this if the alkali and acid are diluted with water, and you wash your hands well afterwards.In summary:Acid + Carbonate --> Salt + Carbon dioxide + WaterAcid + Active Metal --> Salt + Hydrogen

How is a calcite or feldspar inditified?
Calcite can be identified by its rhombohedral cleavage and effervescence in acid. Feldspar can be identified by its two cleavage planes at nearly 90 degrees, and it often has a white to pink color. Both minerals can also be identified by their hardness using the Mohs scale.

Bases create a sour taste in your mouth?
If I remember right bases are a neutral flavor while acids are sour by using the PH Scale.
