杭州千岛湖《农夫山泉》是山泉水
含有一定的矿物质
农夫山泉的瓶子上面写着~
总硬度=钙硬度+镁硬度=4ppm*100/40+0.5ppm*100/24=12农夫山泉的瓶子上面写着~
〉=400微克ca2+
每100ml
〉=50微克mg2+
总硬度每100ml
ca2+=溴4ppm
mg2+=0.5ppm
算一下~
总硬度=钙硬度+镁硬度=4ppm*100/40+0.5ppm*100/24=12
约等于12吧~
不对的话楼下纠正吧~呵呵农夫山泉的瓶子上面写着~〉=400微克ca2+每100ml〉=50微克mg2+每100mlca2+=4ppmmg2+=0.5ppm算一下~总硬度=钙硬度+镁硬度=4ppm*100/40+0.5ppm*100/24=12约等于12吧~不对的话楼下纠正吧~呵呵
