Chemistry

: A suspension of colloids at room temperature(25Â°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))
