: A suspension of colloids at room temperature(25°C) contains CaS04 in (a) 3 mM and (b) 30 mMconcentration. Find the Debye length (in nm) for both the cases.Use relevant data given in lecture 12-13. (c) Why do you supposethe Debye length changes with change in salt concentration? Providereasoning from colloidal science to support your answer. (d) IfNaCI was used instead of CaS04, how would the Debyelength values change for cases (a) and (b)? (No calculationnecessary for part (d))
