Calculate the pH of each of the following aqueous solutions at 25 °C. (Please help me solve #4 with your work, and check my answers for #1-3, if incorrect please show me why, Thank you) 1) 0.65 M boric acid (B(OH)3, Ka = 7.3 x 10-10) (pH=4.66) 2) 3.15 M ammonia (NH3, Kb = 1.76 x 10-5) (pH= 4.37) 3) 0.82 M benzoic acid (C6H5COOH, Ka = 6.3 x 10-5) (pH=2.14) 4) 0.100 M H3AsO4 (Ka1 = 2.5 x 10-4,...
Please rearrange to correct order. Use the pH interactive to classify each item to the proper solution. Assuming equal concentrations, arrange these solutions by pH. Highest to Lowest Ph !! 0.1 M HCI 0.1 M HC,H,O, | 0.1 M NaOH 0.1 M NH, er turns orange weak base pH=1 pH = 13 weak acid pH paper turns blue strong acid strong base RbCl(aq) Mg(CIO)2(aq) RbOH(aq) CHỌNH,Br(aq) HI(aq)
