what an acid

Name of acid 

hydrochloric acid

sulfuric acid

nitric acid 

Phosphoric acid

Acetic acid

Citric acid

Formic acid

Tartaric acid

What is an Acid

An acid is any substance that in water solution tastes sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions

Where do we find acids?

Plaque acid, stomach acid, citrus fruit have citric acid, vinegar

the erebus plane crash november ,28 1979

predictions:
I think this disiter is about a plane people dead some of them savied 
it was an acetone family lost love ones it lands in a building 

coperhechon

1. The plane was heading on a sightseeing trip around Antarctica, seeing McMurdo sound and Scott has  

     2. Captain Jim Collins and First Officer Greg Cassin.
3. The pilot asked to descend to 450m so that the passengers could have a better view.
4. The pilot and co-pilot weren't told about the course change. There was also a whiteout which meant they couldn't tell the difference between the sky, land or snow.
5. November 28th 1979 at 12.49pm.

the notes for the videos 

The plane picked up passengers in Auckland and Christchurch. - the navigation equipment didn't work well near the poles so had issues in Antarctica - Mt Erebus is an active volcano on Ross Island - The plane was only supposed to drop to 6,000 feet when flying near Mt Erebus. - They were 30/40 feet away from where they thought they were because of the course change. -The flight was a sight seeing trip that cost $359 pp - There were 237 passengers and 20 crew on board the flight. - The plane descends to 1500 feet as they make there way around ross island -1249 the alarm tells them to pull up. - Investigators say a serve -bodies had to be chipped out of the ice and snow after the crash.  

-10 police officers were sent down to the Erebus crash site to find the bodies.  

I lean that it was an accident how they are going to stop this in the present  

  
 

 

what is a base

 acid has hydrogen in it 

the strength of the acid has measured the ph 

it goes 0 to 14 which mean each colour has there own number 

red 0 to 1

orange 2 to 3

yellow 4 to 6 

green  7 to 8

blue 9 to 10

indigo 11 to 12 

violet 13 the 14  

a base is an opposite chemical to an acid

a base contains hydroxide (OH)

an acid and a base neutralise each other and make water

red cabbage indicator

 aim: I want to find out how to tell if something is an acid 

method:

equipment 

• beaker
• red cabbage 
• hot water
• test tubes
• acid +hydrooxide
• dropper 

instruction 

1. get your equipment
2. then break a piece of cabbage and put it in the beaker
3. put 100ml of hot water, over cabbage
4. put 2cm of acid in one test tube and 2 cm of hydroxide in another test tube
5. Drop purple cabbage water into each test tube
6. Take a sample of acid and hydroxide to combine to then make purple, blue and green colours 

Results:

the wahine disastrous april 10 1968

 my predictions 

• that people dead 

 

• that there are savivers 

 

• boat crashis 

 the boat will drop to the bottom of the sea there will be a wet floating body

   comprehension

1.  to storms collided  together 
2. wellington
3. 3 lifeboats 
4. jump into the sea and swim to short 
5. because of the lifeboat
6.  53 people dead 200 savied  

   

 

Making Sherbet

Aim:

 I want to find out how to make sherbet 

Research:

method :

.cup 

.baking powder

.icing sugar

.citric acid 

.teaspoon 

wooden popsicle stick

Raro

Instructions:

1 get my cup

2 add icing sugar, baking powder and raro to the cup

3 add half of a teaspoon of citric acid to the cup

4 mix it with the popsicle stick and eat!

result:

it was sour but when I swished it in my mouth it got sweet and it had a sweet taste. It was also fizzy in my mouth.

Conclusion:

 the citric acid when mixed with sodium bicarbonate they create a big volcano thing inside your mouth as the bicarbonate reacts with acid and fizzes
