Define the variable as is the purity of the sodium zeolite synthesis that express the measurement of diffraction analysis tools with x-rays and pressure that occurs in the system, which is measured with a pressure gauge.
Variable according to the purity of the synthesized zeolite sodium X is measured with a X-ray diffraction analysis. And the pressure in the system is monitored by pressure gauges.
The dependent variable is the purity of sodium X zeolite synthesized which measuring with X-ray diffraction analysis tools. And pressure occurring in the system (measured by the gauge pressure.
