    at 15:18 why is the lead a solid if the melting point of lead chloride higher than the melting point of lead on it's own, shouldn't the lead formed be molten too?

    Hi, great video. I just wanted to ask whether at 9:19, the second reaction is actually of neutralization. I am wondering this as water is not a product and hence I thought that the reaction would simply be an acid-base reaction.
