It's just a pH adjuster as indicated by there being two options both of which are just acids (as livo has already pointed out). But the reason you'd want the water to be acidic, rather than basic, is because it produces a soft (or softer textured) rice. And much of the water in the UK is on the basic side of neutral pH.
