QUE SIGNIFIE LIMEWATER EN ANGLAIS
Eau citronnée
Limewater est le nom commun d'une solution saturée d'hydroxyde de calcium. L'hydroxyde de calcium, le Ca2 est peu soluble dans l'eau L'eau de chaux pure est claire et incolore, avec une légère odeur de terre et un goût amer alcalin d'hydroxyde de calcium. Le terme «citron» se réfère au minéral alcalin et n'est pas lié au fruit acide. L'eau de chaux est préparée en agitant l'excès d'hydroxyde de calcium dans de l'eau pure et en filtrant l'excès de Ca2 insoluble. Lorsque de l'hydroxyde de calcium est ajouté à de l'eau de citron, une suspension de particules d'hydroxyde de calcium reste, ce qui lui confère un aspect laiteux, auquel cas il a le nom commun du lait de citron vert. Le lait de citron vert est une solution alcaline avec un pH de 12,3.
