Task 1. Read the text. Circle True or False.
I totally love museums. They really are one of the most important parts of our culture. Museums
are important for so many things. They educate us, they preserve our history, and they show us how
we have developed. There are museums on so many different things. In fact, I'm sure there isn't a
topic there isn't a museum for. I've loved museums since I was little. We used to go to different
museums on school trips. I loved them. I saw so many amazing things. I will never forget seeing the
bones of a T-Rex in the natural history museum. I also remember staring at Tutankhamun's gold mask
for ages. I couldn't take my eyes off of it. The best museum I've ever been to is the National Museum
in Cairo. It's unbeatable.

На нейтрализацию 0,944 г фосфористой кислоты H3PO3 израсходовано 1, 298 г гидроксида калия. Вычислите молярную массу эквивалента, фактор эквивалентности и основность кислоты. На основании проделанных вычислений составьте уравнение реакции.
n(H3PO3) = m/M =0,944 / 82 = 0,0115 моль
n(KOH) = m/M =1, 298 / 56 = 0,0232 моль
n(H3PO3) : n(KOH) = 0,0115 : 0,0232 = 1:2
Отсюда:
Фактор эквивалентности ƒэ (H3PO3) = ½, , так как одна формульная единица фосфористой кислоты обменивает с КОН два иона Н+.
Молярная масса эквивалента Мэ = М ∙ ƒэ = 82 / 2 = 41 г/моль
Основность = 2, т.к. только 2 ат. Н диссоциируют с образованием 2Н+, участв. в реакции нейтрализации.
Уравнение реакции: H3PO3 + 2КОН → К2HPO3 + 2Н2О
