26.（14分）水泥是重大轮要的建筑材料。水泥熟料的主要成分为CaO、SiO2，并含有一定量的铁、铝和镁等金属的氧化物。实验室测定水泥样品中钙含量的过程如图所示：
回答下列问题：
（1）在分裂薯解水泥样品过程中，以盐酸为溶剂，氯化铵为助溶剂，还需加入几滴硝酸。加入硝酸的目的是__________，还可使用___________代替硝酸。
（2）沉淀A的主要成分是_________，其不溶于强酸但可与一种弱酸反应，该反应的化学方程式为_____________。
（3）加氨水过程中加热的目的是___________。沉淀B的主要成分为_____________、____________（填化学式）。
（4）草酸钙沉淀经稀H2SO4处理后，用KMnO4标准溶液滴定，通过测定草酸的量可间接获知钙的含量，滴定反应为：MnO4-+H++H2C2O4→Mn2++CO2+H2O。实验中称取0.400 g水泥样品，滴定时消耗了0.0500 mol·L-1的KMnO4溶液36.00 mL，则该水泥样品中钙的质量分数为______________。
答案：
（1）将Fe2+氧化为Fe3+；双氧水
（2）SiO2；SiO2+4HF=SiF4↑+2H2O
（3）促进Fe3+、Al3+水解；Fe(OH)3、 Al(OH)3
（4）5Ca2+～5H2C2O4～2KMnO4
n(KMnO4)=0.0500mol/L×36.00mL=1.80mmoln(Ca2+)=4.50mmol
水泥中钙的质量分数为4.50mmol×40.0g/mol/0.400g=45.0%
解释：因为一般情况下Mg2+开始沉淀需要pH>8.
金属离子：沉淀形式，开始沉淀pH，完全沉淀pH
Mg2+：Mg(OH)2，8.10，9.43
Fe3+：Fe(OH)3，1.47，2.80
Al3+：Al(OH)3 ，4.20，肆仿者5.37

China’s admiration of outstanding scholars has turned the well-preserved childhood home of TuYouyou, the Chinese pharmacologist who won this year’s Nobel Prize in Physiology or Medicine, into a popular tourist destination.
Since it was announced on Monday that 84-year-old Tu had become the first Chinese citizen to win the international prize, her former home in the old town of Ningbo, Zhejiang province, has attracted visitors, especially parents and their children-even though it is not open to the public.
The house, which is for sale, is part of a complex of 37 traditional buildings, including several city-and district-level cultural relic preservation sites, that have been transformed into a high-end art and commercial zone.
Tu won the prize for developing a lifesaving malaria drug, artemisinin, a staple of traditional Chinese medicine, which has helped save millions of lives across the globe.
“There are continually parents taking their children, from infants in strollers to college students, to take photos in front of Tu’s former home. Security guards have been ordered to go on patrol around the clock,” said a sales person surnamed Zhao, from Ningbo Real Estate Inc Co.
Shanghai resident Xu Lingfei, who was on a trip to Ningbo, took her 9-year-old son to walk around the complex on Wednesday.
“Chinese people believe in exams and awards and have a strong preference for high performers. Taking children to visit the former dwelling places of celebrities is a way to inspire them to study harder,” Xu said.Something similar happened after Mo Yan won the Nobel Prize for literature in 2012.
Tourists started visiting Mo’s former home in rural Gaomi, Shandong province, in an endless stream starting the day after he won the prize. Some even plucked the radishes planted in front of the house and carted away some bricks.
Another site that has become a bigger tourist attraction these days because of Tu’s success is the Luofu Mountain scenic area in Huizhou, Guangdong province, where Ge Hong, a TCM master of the Eastern Jin Dynasty (AD 317-340) picked herbs, developed herbal medicines and wrote the classic Manual of Clinical Practice and Emergency Remedies.
After winning the Lasker Award in the United States in 2011, Tu said she and her team were inspired by Ge’s theory to solve the puzzle in getting artemisinin(青蒿素) from the herb Artemisia annual, also known as sweet wormwood.
A garden and a monument on Luofu Mountain celebrate Ge’s dedication. The mountain is home to 3,000 species of plants, including more than 1,200 with medicinal uses.
