The dip sticks are notoriously inacurate, close enough for a quick check at home but not great. I'd trust the pool dealer results the most, everyone will get a little different results but it's not the end of the world. The dealers usually have good equipment and do a good job of keeping the calibrated, far more acurate then any home test kit.
Standard solutions and titrations are used in analytical chemistry to determine quantitatively the concentations of elements and components of materials. Analytical chemistry is needed in any industry.
Blue litmus become red because the carbonated soft drinks are acidic solutions.
The reference solution in a chemistry lab is the solution that is always present in the experiment, and it doesn't go away while you are testing other solutions. It is kind of like a base camp for your experiment; you're always starting off or going to include it.
The Nobel Prize in Chemistry 1901 was awarded to Jacobus H. van t Hoff in recognition of the extraordinary services he has rendered by the discovery of the laws of chemical dynamics and osmotic pressure in solutions.
Well, from my syllabus which is IB, i would say the most important are Oxidation and reduction, Stoichiometry, Organic Chemistry, Acids and Bases and energetics. There are others but they aren't too difficult to learn or apply and aren't purely chemistry such as Kinetics.
How many solutions does an inconsistent system have
An inconsistent equation (or system of equations) is one that has no possible solutions.
inconsistent
An inconsistent equation (or system of equations) is one that has no possible solutions. That is precisely why we call it inconsistent; there is no solution set that can be substituted for its variable or variables that will make the equation (or system) true.
If a system of equations is inconsistent, there are no solutions.
Any system of linear equations can have the following number of solutions: 0 if the system is inconsistent (one of the equations degenerates to 0=1) 1 if the system is linearly independent infinity if the system has free variables and is not inconsistent.

A chemistry is a subject which deals with chemicals and solutions to create a new substance.
A set of equations is inconsistent, if its solution set is empty.
Chemistry is mainly used in laboratories to prepare chemical solutions and drugs.
Whatever they are, they are NOT in solution. They are contaminants.
