Answer 1

One simple solution is to use the Unicode subscript range, U+2080 through U+2089. Example: 2 H₂ + O₂ -> 2 H₂O.

You can type one of these characters by using the Unicode Hex Input keyboard layout, holding Option, and typing the hex digits (e.g. hold option and type “2080” for “₀”).

Given a single digit, you can format it into a string as a subscript like this:

static const unichar kSubscriptZero = 0x2080;
int numberOfHydrogens = 2;
NSString *water = [NSString stringWithFormat:@"H%CO",
    kSubscriptZero + numberOfHydrogens];
