it is universal indicator with mixture of alkali
What happens when you add alum to water?
crystals form
How do you measure the acidity of acid rain?
You add universal indicator and then compare the colour it turns to an example ph scale. The redder the Ui the more acidic it will be, if it is green it will be neutral and if it is blue/purple it will be alkali.

When you dissolve magnesium oxide with water and add universal indicator what colour do you see?
When magnesium oxide dissolves in water and universal indicator is added, the solution may turn blue or purple. Universal indicator changes color based on the pH of the solution, and in this case, the basic nature of magnesium oxide may cause the solution to shift towards these colors.
What color will river lake or stream turn if you add universal indicator?
green as most lakes and rivers are fresh water, so neutral.
Describe how you would measure PH of an unknown liquide?
Add universal indicator.
What happens to water when add indicator?
water is pretty neutral in terms of the pH scale, so nothing should happen unless you have poisoned water .It'll turn green if you used universal indicator(pH7), after you added it, the water is posioned you can't drink it
When the reaction with potassium had finished what would happen if you added universal indicator solution to the water?
If you add universal indicator solution to the water after the reaction with potassium, the indicator will change color depending on the pH of the solution. Potassium reacts with water to form potassium hydroxide, which is a strong base. The solution will likely turn purple or blue indicating a high pH.
How to check pH value using universal indicator?
To check pH value using universal indicator, you can add a few drops of the indicator to the solution you want to test. The color it turns will indicate the approximate pH of the solution based on the color chart provided with the indicator. Match the color of the solution to the chart to determine the pH value.

How do you make a universal indicator?
Universal indicator is an aqueous solution of many indicators: methanol, propan-1-ol, phenolphthalein sodium salt, methyl red and monosodium salts of bromothymol blue and thymolblue. Most of these have a very complicated process associated with it during its manufacture.
