填空题

(14分) 卤化物和卤酸盐在工业生产中有着重要的作用。某小组为探究其中一些盐的性质,查阅资料并进行实验。查阅资料如下:

① BrO3 + 6I + 6H+ = 3I2 + Br+ 3H­2O    ② 2BrO3 + I2 = 2IO3 + Br2

③ IO3 + 5I + 6H+ = 3I2 + 3H2O           ④ 2IO3 + 10Br+ 12H+ = I2 + 5Br2 + 6H2O

实验如下:

步骤现象
ⅰ.向盛有30 mL 0.2 mol·L-1 KI溶液的锥形瓶中依次滴入几滴淀粉溶液和足量稀硫酸,再用滴定管逐滴加入KBrO3溶液随着KBrO3溶液滴入,溶液由无色变为蓝色并逐渐加深,最终保持不变
ⅱ.继续向上述溶液中滴入KBrO3溶液溶液的蓝色逐渐褪去
请回答:

(1)步骤ⅰ开始时发生的反应如资料①所示,溶液中I完全被氧化时转移     mol电子,该反应中硫酸表现出的化学性质是                  

(2)上述资料中的反应              (填序号)可表示步骤ⅱ中的反应,通过该反应         (填“能”或“不能”)说明碘的非金属性强于溴,原因是               

(3)根据资料中的反应①~④并结合所学知识,判断IO3、BrO3、I2、Br2的氧化性由强到弱的顺序是                ;KBrO3溶液与KBr溶液在酸性条件下反应的离子方程式是                                         

(4)若用y表示锥形瓶中含碘物质的物质的量,用x表示所滴入KBrO3的物质的量,在下图中画出上述整个实验过程中y随x的变化曲线(要求:在图中标出终点坐标)。
