Compare destructive and non-destructive testing
Destructive: is when the root word of the testing reply is altered by the chemical analogue and hence the original sample is not recoverable. E.g. testing pH of a sample exploitation an indicator.
Non-destructive: is when the composition of the testing solution is not altered and the original sample can be reused after testing. E.g. testing pH of a sample using a pH meter.

Describe qualitative and/or quantitative tests for hardness, turbidity, and acidity (pH) in locate to analyse and compare the shade of urine samples
Hardness:
Hardness is due to the presence of meaningful concentrations of calcium and magnesium ions in the water.




Hard water is water that does not lather with scoopful and which leaves a grey folderol around baths and basins; if the water is not hard(and with very low concentrations of calcium and magnesium), then it is called fluffy water.
Ca2+(aq) + 2C17H35COO-(aq) ? Ca(C17H35COO)2(s). The precipitate is also written as (C17H35COO)2Ca
Mg2+(aq) + 2C17H35COO- (aq) ? Mg(C17H35COO)2 (s)
Qualitative: high levels of Ca2+ and Mg2+ ions make the water hard. This means soap doesnt lather (form froth). Sydney water is identified as soft water as its hardness lies between 10 40 ppm.
Soft water: < 75 ppm
Hard water: one hundred fifty 500 ppmIf you want to get a full essay, order it on our website: Orderessay
