Trộn 2 lít dung dịch A 0,2M vào 2 lít dung dịch B 0,1 M, có phản ứng thuận nghịch: 2A+ B --> A2B. Khi đạt cân bằng thì nồng độ A trong dung dịch bằng nồng độ A2B. Tính hằng
số cân bằng Kc của phản ứng. Biết rằng các chất đều nằm trong dung dịch và thể tích dung dịch
là 4 lít.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
