A. Each group will need ~7 solutions where a single BCG Bromocresol Green concentration exists (~2 x 10-5 M) with different concentrations of NaCl (0.02M-0.2M). Compute the preparation scheme to prepare these solutions using the subsequent concentrations specified for NaCl. 0; 0.002; 0.004; 0.006: 0.008; 0.01; 0.03; 0.05; 0.08; 0.1; 0.2M
B. Explain what would be the ionic strength for these solutions?
