Question

what will be the ph value 1.0 m hcl solution and 1.0 m kcl solution assuming that the substances are fully ionised​

Answer 1

Answer:

HII

Explanation:

Let us suppose that you have available 37 wt% hydrochloric acid of some commercial brand (reagent grade). Unless stated otherwise, the concentration indicated in the label, should be assumed as given in wt%. The corresponding (approx.) density should be available from the label, but we can also take it as 1.184 g·cm-3 (cf. e.g. Perry's Chemical Engineers' Handbook). The molecular mass of HCl is 36.46 g·mol−1. From this data the molarity of the conc. sol. is readily calculated. The intended dilute solution (1 M) should be prepared by considering the appropriate (volumetric) dilution factor.
