<span lang="EN-US" style="font-family: "Times New Roman","serif"; mso-ansi-language: EN-US;">Jawaban:</span></div>
<div class="MsoNormal" style="margin-bottom: .0001pt; margin-bottom: 0cm;">
<span lang="EN-US" style="font-family: "Times New Roman","serif"; mso-ansi-language: EN-US;"><span style="mso-tab-count: 1;"> </span>Tingkat keasaman larutan (pH) dapat
mempengaruhi kelarutan dari berbagai jenis zat. Suatu basa pada umumnya lebih
larut dalam larutan yang bersifat asam, dan sebaliknya lebih sukar larut dalam
larutan yang bersifat basa. Garam-garam yang berasal asam lemah akan lebih
mudah larut dalam larutan yang bersifat asam kuat.</span></div>
