What Are Acids & Bases? | Chemistry Basics

Acids and bases can be found all throughout your everyday life and are often times very useful… even in your own body! But what is it about acids that make some super dangerous and other safe to eat? And in order to tell how acidic or basic a chemical is, how do we measure their individual intensities? This episode of chemistry basics covers the fundamentals of acids and bases and how we use the pH scale to measure them.

• What is a hydrogen ion?
A hydrogen atom that has lost it's one, and only, electron
• All acids produce H+ Ions when dissolved in water
• What determines if an acid is safe to eat?
How much H+ an acid produces determines whether it can be eaten or not
• What is the pH scale?
A method of quantifying acidity by converting H+ Ions concentrations in a value between 0-14
• What is the range of values on the pH scale?
0-14
• What pH values do acids have (range)?
Bellow a 7
• The lower the number on the pH scale, the higher the H+ concentration
• The pH scale is logarithmic, which means each value on the pH scale means 10 times concentration of H+.
• What pH values do bases have (range)?
Above 7
• What pH value shows that something is neutral?
7
• Give an example of a neutral substance.
Pure water
• What do bases do to hydrogen ions?
Accepts them
• What ions do bases produce in water?
OH- Ions
• Complete this equation:
Hydrogen ion + Hydroxide ion = water
What is this reaction called?
Neutralization Reaction
Why do you think it is given this name?
It neutralizes the pH level of the substance

Examples of acids used in everyday life:
yogurt
vinegar
lemon juice
citric acid
apples
Examples of bases used in everyday life:
drain cleaner
laundry detergent
lubricating grease
alkaline batteries
soaps and bath products

This is the final assignment from my all time favorite teacher. She has us watch this video. I’m going to remember her no matter what. Miss Perry is you are reading this I want you to know I absolutely adored your class and am forever greatful for everything you’ve taught me!

Even i made the vid speed at 0.5x to catch up, my brain stopped at 2.14s.

Anyways thanks for the vid. What i get is..

1. Acid produces hydrogen ion (H+)
2. Base (alkaline) produces hydroxyl ion (OH-)
3. Acid (pH 0-6) got more H+ than alkaline (8-14)

Wow this vid is very useful! It summed up an hour of textbook work in 3 min!

this vide is amazing and has taught me so much but its too fast

1:34 Isn’t it called ammonium hydroxide? Ammonia is the gas dissolved in the water in ammonium hydroxide.

Wow I learn about the ph scale and how it’s important

[danniheggie]

thanks for the information very concise and clear.
