Testing for ACids and Bases Lab

What we did in class, we took different solutions and tested to see their reactions in different indicators, to differentiate if it’s an acid base or neutral.

Why did we did this, learning the indicators and their reaction rates with other solution is crucial in chemistry. Even if we didn’t know what the solution was we could find out by using indicators and learn if it’s an acid base or neutral in a safe way.

How this is used in the real world? Sulfuric acid, Acetic acid, Sodium Hyrdoxide are all acids and bases commonly found in the real world with real world applications. Ex/ Acetic acid is used in the manufacture of ink and dyes, of pesticides and food preservatives and of rubber and plastic.

Reaction Rate Analogy

So if you want to increase the amount of car crashes you must increase the size of the cars that means they have higher chance of hitting eachother. Then lessen the width of the roads, so they have less of a chance of escaping. More cars, if you have more cars on the road you have more of a chance of colliding with others. Remove signs and lines, so that people are unaware of where and how fast they are going. Then cover the roads with ice, to make sure they hit eachother with a deadly amount of force.

Motion and position and Uses

When an object moves it can be graphed on a time graph with it’s position and movement

 

The use of motion and position in real life:

 

It is used in many control and machinery applications.

Example: For motion control applications  which includes systems for manufacturing, transportation, construction and energy production – position sensors enable the control system to be ‘aware’ of the physical location of the mechanical components that it controls.
