What can bases turn red litmus paper into? A. Red B. Blue C. Green D. Yellow 相关知识点: 试题来源: 解析 B。解析:文中提到 Bases, on the other hand, taste bitter and feel slippery. They can turn red litmus paper blue. 碱尝起来是苦的,摸起来很滑,能使红色石蕊试纸变蓝。
A. Feels slippery B. Turns litmus paper red C. Does not react with acids D. Has a sour taste 相关知识点: 试题来源: 解析 A。本题考查碱的性质。碱摸起来滑滑的,A 正确;碱能使石蕊试纸变蓝,不是变红,B 错误;碱能和酸反应,C 错误;碱尝起来是涩的,不是酸的,D 错误。反馈...
red litmus paper remains red. In an alkaline solution, red litmus paper turns blue. When an alkaline compound dissolves in water, it produces hydroxide ions, which cause the solution to become alkaline. Red litmus paper can also be used to test...
It will turn red C. It will turn black D. It will not change color 相关知识点: 试题来源: 解析 B。解析:柠檬汁是酸性物质。石蕊试纸(litmus paper)遇酸性物质会变红,遇碱性物质会变蓝。因为柠檬汁是酸性的,所以石蕊试纸会变红,而不是变蓝、变黑或者不变色,所以A、C、D错误。
