What does turbidity measure?Group of answer choicesThe toxicity of the waterThe clarity of the waterThe temperature of the waterThe salinity of the water

Turbidity estimates the number of viable cells in a clear liquid media or broth.

A sample of seawater collected at a beach in Singapore was analysed. It was found to have a turbidityof 15 NTU. For reference, the range of turbidity of drinking water in Singapore is 0.05 – 0.51 NTU.Raw sample Treated sampleTurbidity (NTU) 15 1Absorbance(unitless)0.7 0.05(a) At 25°C, the pKw of seawater is 13.22. This value is lower than that for water as a result of thedissolved salts. If the pH of a sample of seawater is 6.78, what is the pOH of the sample? (1 point)(b) At pH of 6.78 and pKw of 13.22, is this sample of seawater acidic, basic or neutral? Briefly explainwhy. (2 points)(c) The sample is treated to reduce its turbidity. Name one method that can be used to reduce theturbidity of the water sample. (1 point)(d) What is the % transmittance of the raw sample? (1 point)(e) A spectrometer is used to analyse the absorbance of the treated sample. Determine the % of lightabsorbed in the analysis of the treated sample (assume negligible reflection and scattering).(2 points)
