Answer:
1) False, acids have a low pH
2) bases are slippery
3) water and salt
4)i think its strong acid but not completely sure
5) neutral
Explanation:
Answer:
4.921.
Explanation:
- It is an acidic buffer solution;
∵ pH = pKa + log[salt]/[acid].
<em>∴ pH </em>= - log(1,8 x 10⁻⁵) + log[0.75/0.50] = 4.745 + 0.1761 = <em>4.921.</em>
