'''탄산 나트륨'''(Na<sub>2</sub>CO<sub>3</sub>)은 [[화합물]]의 한 종류로, [[탄산]]과 [[수산화나트륨]]의 [[염]]이다. [[유리]]에 주로 포함되어 있어 [[빛]]이 통과할 때 [[자외선]]을 차단해 주는 역할을 하기도 한다. [[상수도]]에서 [[정수 (물)|정수]] 과정 중 [[pH]]를 조절하기 위해 사용되기도 한다.<ref>{{서적 인용 |저자=노재식 외 |날짜= 2016|제목= 토목기사 대비 상하수도 공학|출판사= 한솔아카데미|쪽=158-159 |isbn=979-11-5656-234-4}}</ref> 탄산 나트륨은 나트륨 이온(Na<sup>+</sup>)이 포함되어 있어 물에 잘 녹는다.<ref name="완자">{{서적 인용|저자= 김봉래 외 2 |제목= 완자 화학 Ⅰ(1권)|날짜= 2006-07-01 |판= 초판 |출판사= 비유와상징|쪽= 29}}</ref>
