Hasil validasi ahli terhadap aspek kesesuaian isi, keterbacaan, dan kemenarikan memiliki rata-rata persentase sebesar 89,35% dengan kategori sangat tinggi. Berdasarkan tanggapan guru terhadap aspek kesesuaian isi diperoleh persentase sebesar 90,28%, konstruksi sebesar 91,25%, dan keterbacaan sebesar 87,77% yang berkategori sangat tinggi. Berdasarkan tanggapan siswa pada aspek keterbacaan diperoleh persentase sebesar 93,11% dan kemenarikan sebesar 92,36% yang berkategori sangat tinggi.Sehingga LKS dapat dikatakan valid dan layak untuk digunakan.Kata kunci: Lembar Kerja Siswa, perubahan konseptual, titrasi asam basa
