Potassium by flame-ionisation color test: redish purple
Sulfate: by Barium chloride suspension test ( BaSO4)solid
pH strips are used to determine whether a solution is acidic or basic
n
To determine what the white substance is we must add it to HCl.
If the solution will conduct electricity it is ionic. Solutions made from molecules do not conduct electricity.
to indicate the changes of colour and to determine whether displacement of halogen occur
pH strips are used to determine whether a solution is acidic or basic
Whether or not it's an acid or a base
Whether or not that there is a solution to a quadratic equation,
I don't believe it is a solution.

Test it with Benedict's solution.
You substitute the coordinates of the point in the equation. If the result is true then the point is a solution and if it is false it is not a solution.
This solution may be toxic, corrosive or radioactive.
To determine what the white substance is we must add it to HCl.
An equation can be determine to have no solution or infinitely many solutions by using the square rule.
it is base
