請問湯力水(tonic) 和梳打水(soda)有甚麼分別?

Tonic water (or Indian tonic water) is a carbonated soft drink flavoured with quinine. (Quinine 即奎寧，又名金雞納，是一種帶苦味的樹皮)。

Carbonated water, also known as soda water, sparkling water, fizzy water or seltzer water, is plain water into which carbon dioxide gas has been dissolved.

Tonic Water 味帶苦，Soda Water只有汽，冇(或有些少咸味)味。

Tonic 通常加Gin (Gin-Tonic)或加於Vermouth中做Martini。
Soda 通常加於威士紀 (Whiskey soda)或於cocktail 中代替7-up，以減少甜味。

湯力水(tonic water) 有些微苦味，
梳打水(soda)有汽，似冇味汽水。

tonic can go with vodka
soda can go with anything
