Can strong and weak acids be determined by using an indicator?
Indicators can determine whether a solution is acidic or basic based on a color change. However, indicators do not differentiate between strong and weak acids since they only indicate the presence of hydrogen ions in a solution. Strong acids fully dissociate in water, releasing all their hydrogen ions, while weak acids only partially dissociate, but indicators cannot distinguish between the two.
Is it true that for binary acids the hydrogen pert of the compound is named using the prefix hydro?
Yes, for binary acids (acids composed of hydrogen and a non-metal), the hydrogen part of the compound is named using the prefix "hydro." This is common in binary acids such as hydrochloric acid (HCl) and hydrofluoric acid (HF).
What structure liquefies foods using acids and begins protein digestion?
The name of that structure is stomach. Your stomach starts to digest the food. So the food becomes more liquid. It uses very strong acid for this purpose. The acid is hydrochloric acid. It is wonderful to have such strong acid to be used in your body.
You are given a colourless solution Describe three tests you would carry out to determine whether the solution is an acid or an alkali without tasting or using indicators?
Test for electrical conductivity: Acids conduct electricity in solution due to the presence of hydrogen ions, while alkalis conduct electricity due to the presence of hydroxide ions. By testing the electrical conductivity of the solution using a conductivity meter, you can determine whether it is acidic or alkaline based on the level of conductivity observed. Test for reaction with metals: Acids react with active metals such as magnesium or zinc to produce hydrogen gas. Alkalis, on the other hand, do not react with metals in the same way. By adding a small piece of metal to the solution and observing for the formation of gas bubbles, you can deduce whether the solution is acidic or alkaline. Test for reaction with carbonate compounds: Acids react with carbonates to produce carbon dioxide gas, while alkalis do not react with carbonates in the same way. By adding a small amount of carbonate compound, such as baking soda, to the solution and observing for the effervescence of gas bubbles, you can determine whether the solution is acidic or alkaline.
What is a pH scale How do you make a pH scale pls answer FAST?
its something used to see whether a substance is an acid or alkali. the scale is as follows 1-3 is a strong acid 4-6 is a weak acid 7 is neutral (distilled water) 8-9 is weak alkali 10-14 is a strong alkali
What three things should you always do when using acids or alkalis in the labrotory?
put safety glasses on
How can Acids and Alkalis be identified using an PH scale?
The pH scale has values ranging from 0-14. A substance with pH between 0-6 is considered as an acid, one with pH 7 is considered neutral while substances with pH in range 8-14 are considered as bases.
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.
When should ipecac not be used for poisoning?
Using ipecac can make certain kinds of poisoning worse and should not be used to treat strychnine, alkalis, strong acids, kerosene, fuel oil, gasoline, coal oil, paint thinner, cleaning fluid poisoning.
Can strong and weak acids and strong and weak bases be determined by using an indicator?
yes
How can you tell if it is an alkali?
by adding hydrochloric acid to the substance, and if it turns red its a strong acid, if it turns blue its a strong alkali. if its a colour in between like greeny blue or reddy orange, it means it not as strong. Green is neutral XD
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).
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.
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
What products contain strong acid?
Products that contain strong acids include battery acid, hydrochloric acid in household cleaners, and nitric acid in some metal polishes. These acids can be corrosive and harmful if not handled properly. It is important to follow safety guidelines and usage instructions when using products containing strong acids.
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.
