experiment with red cabbage

 Welcome,  everyone to my blog again. i hope you are well. Today my blog is about (experiment with red cabbage)So, let's go to main work .....

Experiment: Red Cabbage indicator.

Equipment:

1. Red Cabbage

2. Knife

3. Bunsen Burner

4. Beaker

5. Water

Method:

1. Cut the cabbage into small pieces.

2. Place the cabbage in the beaker and fill it with 50 ml of water.

3. Once the cabbage has boiled for 2 minutes turn it off and leave it to cool down.

4. Once it has cooled remove the cabbage leaves and use the red water as an indicator.

Do you know By using red cabbage as an indicator we can determine what the pH level is of substances.

pH indicators

Acid solutions, have lower pH. Alkaline solutions, have higher pH. Substances that aren't acidic or alkaline (that is, neutral solutions) usually have a pH of 7. Acids have a pH that is less than 7. Alkalis have a pH that is greater than 7. 

Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically. pH is reported in "logarithmic units". Each number represents a 10-fold change in the acidity/basicness of the water. Water with a pH of five is ten times more acidic than water having a pH of six.

Baking soda

 

Baking Soda

Baking Soda is also known as Sodium Bicarbonate.Due to its abrasive and cleaning properties it is used as a raising agent in baking, as a household cleaner and in a number of other ways.

Making Sherbet

Blind Taste-Test

 Aim: To taste foods that are sweet, bitter, sour or salty.

In pairs, while Person 1 is tasting, Person 2 will be writing down what they think it tastes like on their chart.

Use the chart below to record your responses.

Equipment

1. Samples 1-9

2. Blindfold glasses

3. Recording chart

4. Ice cream stick taster

Method:

1. Get safety glasses and make a blinfold.

2. Set up your chart and make sure that the person you are working with knows where to record your responses.

3. Using an ice-cream stick you will dip it into the Sample. Once the sample is on the stick you will taste it and tell your partner your response.

4. There will be 2 Answers.

5. At taste test one you need to hold your nose.

Answer 1. Is it sweet, sour, salty, bitter. Record it.

Answer 2. What do you think it is. Record it.

6. Repeat this for the next samples but you will only need to use your icecream stick taster for samples 1-4.
