Photos Or Videos of Experiment.

I didn't get any videos because I had to leave early so I will add an internet photo.

Discussion:

What is an acid and a base?

An acid is a contributing product containing hydrogen ions. Now the solution contains more hydrogen ions than hydroxide ions. That form of solution is acidic. A foundation is a material capable of consuming hydrogen ions. As a base is dissolved in water the equilibrium between hydrogen ions and hydroxide ions changes in the opposite direction.

What do chemical indicators do?

chemical indicator, any substance that gives a visible sign, usually by a color change, of the presence or absence of a threshold concentration of a chemical species, such as an acid or an alkali in a solution. The common application of indicators is the detection of endpoints of titrations.

Results:

I didn't get a photo so I will explain how mine tasted like.

It tasted super sour and super sweet. 🤩🤩🤩

Discussion:

Why did the sherbet not foam on the paper but it did in your mouth?

Because it was dry.

What was the chemical reaction of the sherbet?

The chemical reaction creates a fizzing feeling in your mouth because of your liquid which was your saliva.

What type of chemical reaction is this?

A neutralisation reaction.

Discussion:

How do you taste food:

The taste buds pick up clues about how food tastes and send messages about it to your brain along special wires called nerves. To taste something properly, you need to chew food into small pieces and have a lot of drool, or saliva. This helps the flavor molecules (also known as “tastants”) reach your taste buds.

What are the different taste buds of our tongue: Taste buds contain the taste receptor cells, which are also known as gustatory cells. The taste receptors are located around the small structures known as papillae found on the upper surface of the tongue, soft palate, upper esophagus, cheek, and epiglottis.

Does smell affect your taste:

Our sense of smell is responsible for about 80% of what we taste. Without our sense of smell, our sense of taste is limited to only five distinct sensations: sweet, salty, sour, bitter, and the newly discovered “umami” or savory sensation. All other flavors that we experience come from the smell.

Eating Hot Chilli

the second one with water 0/10

the third one with coke 0/10

fourth one with milk 0/10

Discussion:

Why does chili burn your mouth? 

1. because of something called capsaicin which is measured in Scoville.

2. chili doesn't only burn your mouth, it can burn your eye.

Why did the milk help?

3. because it's cold.
