Question
The locus of x2 + y2 + z2 = 0 is
- (0, 0, 0)
- a sphere
- a circle
- none of these
Hint:
We are given an equation. We have to find the locus of the equation.
The correct answer is: (0, 0, 0)
The given equation is x2 + y2 + z2 = 0
The solution of the equation should be real numbers.
The only real numbers that will satisfy the above equation is if all three variables are zero. The reason is all the terms are squares. So, squares are always positive.
So, the locus of the equation is (0,0,0)
For such questions, we have to be careful about points satisfying the equation.

Aqueous solution of phosphoric acid with a density oflg mL-1 containing 0.05% by weight of phosphoric acid is used to impart tart taste to many soft drinks. Phosphate ion is an inteife ring radical in qualitative analysis. It should be removed for analysis beyond third group of qualitative analysis
the basicity of phosphoric acid is:
Chemistry-General
Chemistry-
The product of the concentrations of the -ions of an electrolyte raised to power of their coefficients in the balanced chemical equation in the solution at any concentration. Its value is not constant and varies with change in concentration. Ionic product of the saturated solution is called solubility product ![K subscript s p end subscript](data:image/png;base64,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)

The product of the concentrations of the -ions of an electrolyte raised to power of their coefficients in the balanced chemical equation in the solution at any concentration. Its value is not constant and varies with change in concentration. Ionic product of the saturated solution is called solubility product ![K subscript s p end subscript](data:image/png;base64,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)
